It can be controlled directly by Micro-controller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) Review: This board + Raspberry Pi + good power supply = A great combination! - Excellent board for Raspberry Pi. Assuming you have a solid power supply, you can run this board off the +5v provided on the pin header (Pin #2). The relay board is fully buffered, meaning that the relay coils are not directly driven from the GPIO pins which protects the Pi and means that this board is plug and play. If you're going to be doing a lot of work with the RasPi, I highly recommend a USB voltmeter/ammeter combo so you can monitor your power usage. At full load, you want to ensure that your voltage on your USB port is as close to 5.0VDC as possible, anything less than 4.65VDC will cause problems with the Pi and stability. Your amperage should never exceed the USB power supply's capability. I use a 2A (2000mA) power supply and with full load (all relays on), the board + Raspberry Pi B+ only gets to .56A (560mA) so I'm well with spec. With all relays off, I pull about .24A (240mA) HOW TO HOOK IT UP: The board has a six pin header labeled GND, IN1, IN2, IN3, IN4, VCC and a two pin jumpered header labelled VCC/JD-VCC. Leave the jumper installed. For GND, you can connect to any of the GND pins on the Pi's header (Pins 6,9,14,20,25,30,34,39). For VCC, connect to pin 2 (+5V). Connect each of the IN pins to a GPIO pin (I used GPIO 8,9,10,11 which are pins 24,19,21,23 respectively). HOW TO CONTROL IT: Use Python (should be available in your RasPi distro) along with the RPI.GPIO library. You'll need to run your scripts with sudo as manipulating the GPIO pins requires root access. You can set the GPIO pin using GPIO.output(PIN, True) to turn off the relay, and GPIO.output(PIN, False) to turn it on. My only nitpick is that the logic is backwards. Driving a GPIO pin high (TRUE), should turn on the relay while driving the GPIO pin low (FALSE) should turn it off, but it's easily fixed in software. Pros: Plug and play, just works. Will be getting more of these. You don't have to worry about building interface circuits, transistors, load calculations down to the mA or anything overly complicated. Basic research into the GPIO library for Python, a couple of GPIO pinouts for the RasPi and I was up and running within minutes. Cons: Logic is backwards, you have to send a GPIO pin LOW to turn on the relay but this is a very minor thing and can be easily fixed in software. Verdict: If you are looking to be able to control equipment using a Raspberry Pi, this is the board to use. Review: Another part of a project- works great though. - Bought these for a Raspberry Pi project. Haven't finished yet but this part itself is solid, well built, and ready for business. Will probably be buying a lot more if my product works the way I expect. Buy this if you need it. ## Features - Equiped with high-current relay, AC250V 10A ; DC30V 10A - 5V 4-Channel Relay interface board, and each one needs 50-60mA Driver Current - Be able to control various appliances, and other equipments with large current - Application：Supports all MCU control, The industrial field, PLC control, Smart home control - Indication LED's for Relay output status ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00KTEN3TM | | Best Sellers Rank | #547 in Single Board Computers (Computers & Accessories) | | Brand Name | JBtek | | Coil Voltage | 5 Volts | | Connector Type | Through Hole | | Contact Current Rating | 10 Amps | | Contact Material | Silver, Copper, Or Alloy | | Contact Type | Form C Or Spdt | | Current Rating | 10 Amps | | Customer Reviews | 4.6 4.6 out of 5 stars (602) | | Item Weight | 9.07 g | | Manufacturer | JBtek | | Maximum Switching Current | 10 Amps | | Minimum Switching Voltage | 5 Volts | | Model | 4450182 | | Mounting Type | PCB Mount | | Operation Mode | Automatic | | Part Number | RP0009 | | Specification Met | Ma | | UPC | 520361134553 | ## Product Details - **Connector Type:** Through Hole - **Contact Material:** Silver, Copper, Or Alloy - **Contact Type:** Form C Or Spdt - **Current Rating:** 10 Amps - **Mounting Type:** PCB Mount ## Images ![4 Channel DC 5V Relay Module for Arduino Raspberry Pi DSP AVR PIC ARM - Image 1](https://m.media-amazon.com/images/I/71LyrM2tGcL.jpg) ![4 Channel DC 5V Relay Module for Arduino Raspberry Pi DSP AVR PIC ARM - Image 2](https://m.media-amazon.com/images/I/71r2aSbFEFL.jpg) ![4 Channel DC 5V Relay Module for Arduino Raspberry Pi DSP AVR PIC ARM - Image 3](https://m.media-amazon.com/images/I/71iSEtibI+L.jpg) ## Questions & Answers **Q: How is this compatible with raspberry pi if it is 5v ttl? can i connect it to a raspberry pi and what voltage level activate it?** A: There's a driver circuit per relay on the board. The IN1 through IN4 inputs can be driven by a 5V or 3.3V logic signal, but the board needs to be configured properly. In my case the relay inputs were connected to the 3.3V GPIO outputs of an ESP8266 NodeMCU board. For 3.3V drive levels, do this: 1. Remove the jumper on the relay board between JD-VCC and VCC. 2. Connect VCC on the relay board (which powers the input circuits) to the 3V3 of the NodeMCU or Raspberry Pi GPIO Expansion connector. 3. Connect JD-VCC on the relay board (which powers the relay coils and driver circuits) to VIN of the NodeMCU or 5V of the Raspberry Pi GPIO Expansion connector. A logic low level on the relay board input activates the corresponding relay. A logic high level on the relay board input or floating input leaves the corresponding relay deactivated. Each relay consumes 68mA from JD-VCC (for the driver and relay coil combined) when one relay is in the activated state. So, when one relay is activated that's 68mA, or 4 * 68mA = 272mA from JD-VCC if all four relays are activated simultaneously. **Q: What is the third screw terminal for? i know one is gnd in and the other is gnd to accessory, but the control pins are on the other side.** A: Answers claiming that the leftmost terminal is common are wrong. The center terminal is common, leftmost (shown connected to the center terminal with silkscreen) is NC 'normally-closed', and the rightmost of each triplet is NO 'normally-open' **Q: Can the arduino/rpi drive this directly or are external drivers required?** A: RPI=Yes. The current flowing through inputs IN1 - IN4 comes from Vcc, a 5V supply and is limited by two diodes and a 1000ohm resistor so it will be about 3mA IF the picture here is the same as the board you receive. Board schematic: http://wiki.sunfounder.cc/index.php?title=4_Channel_5V_Relay_Module . More information you may need: According to the description here, the power supply will need to supply 50-60mA for each relay that is energized. No, you will need about 100mA per relay. The data sheet for the relay in the product picture http://www.datasheetspdf.com/datasheet/download.php?id=720556 says the relay coil requires 89.3mA. This is only the current that flows through the relay coil. Add to that the current the goes to the RPI and the current that drives the transistor that drives the relay coil and it adds up to about 100mA/relay. Hyetex **Q: Is diode stuff embed? do i need to hook it with external diode and pnp ect.?** A: External diode is embedded in the circuit ## Customer Reviews ### ⭐⭐⭐⭐⭐ This board + Raspberry Pi + good power supply = A great combination! *by M***T on March 22, 2016* Excellent board for Raspberry Pi.

This is the first time I've ever used a multi-channel relay board with an Arduino. The build seemed to comparable to brand-name Arduino card. It's mechanical so there's a click -- you can hear it in the video. All pins were well marked, each channel has its own SMD to let you know when it's active. Terminals screwed down tight. Nothing about it was an issue. I saw some complaints before I ordered it so I was a little nervous but most of them regarded the lack of documentation. It does require a certain knowledge base. There's an Instructable: [...] I'm probably going to order a few more just to have on hand. ## Frequently Bought Together - JBtek 4 Channel DC 5V Relay Module for Arduino Raspberry Pi DSP AVR PIC ARM - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Gikfun 12V DC Dosing Pump Peristaltic Dosing Head with Connector For Arduino Aquarium Lab Analytic Diy AE1207 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/81127945-4-channel-dc-5v-relay-module-for-arduino-raspberry-pi](https://www.desertcart.dk/products/81127945-4-channel-dc-5v-relay-module-for-arduino-raspberry-pi) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-24*
