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 ## 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.kr/products/293196940-4-channel-dc-5v-relay-module-for-arduino-raspberry-pi](https://www.desertcart.kr/products/293196940-4-channel-dc-5v-relay-module-for-arduino-raspberry-pi) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-06-01*
