A Relay Circuit with 8 Channels. It needs 5V and the Signal Lines have a Resistor, so the current is limited and wont damage a Microcontroller.
Product was tested and works successful.
# ESP8266 I/O shield #
Main board for inputs and outputs multi IO for for exemple central heating system with FET outputs, relais outputs and 1-wire connection.
Need an ESP 8266 devboard.
On board 5V and 3.3V from 12 to 24V input.
Used this before making the one with ESP32 and more I/O and calculation power.
Works fine for many uses.
ESP code generated by Jeeduino plugin in Jeedom but you may...
Since somyone really cares about this project, I made it more readable ：）
This board contains:
Motor Drivers: Contains two l298n to drive two 550 motors, each chip allows 2A current, and 550 motor uses up to 3A current, that's why I made this special board to drive them. I fit the most common heatsink just onto these chips, CHECK if it fits your heatsink. They are critical.

In this project, we will make a **4-Channel Relay Driver Module Circuit** for relay based applications. In this circuit, we have designed an isolated PCB for 4 relays. By using this **Relay Board**, we can operate 4 AC appliances at a time. We have put a three pin screw terminal blocks (NC, Nuteral, NO) for connecting appliances. Below are the circuit diagram and PCB layout designs of the relay dr...
16 Bit Relay-based 2:1 Mux + Not Unit. Used to implement the Zero and Not functions of the Relay2Tetris ALU
Use PCB-GP for production. It has teardrops and ground-plane.
Relay2Tetris project details here: https://github.com/RJWoodhead/Relay2Tetris
NOTE: This board is being revised; see project notes for more details.
16 bit Boolean Logic Unit. Computes AND, OR, XOR, NAND, NOR, XNOR plus TRUE and FALSE.
Use PCB-GP for production. It has teardrops and ground-plane.

NOTE: This board is being revised! Not suitable for production.
As this is an active project, I suggest you check with me in the unlikely event you decide you actually w...
16-Bit Register Design - Rev 4.1
Includes 2:1 MUX, register, and bit test unit; all components optional.
PCB-GP is production-ready; it has teardrops and ground-plane. If not present, it means minor tweaks are ongoing.
Version 4.0 has numerous improvements, including fatter traces, better power input. Strongly suggest that 12v relays be used due to voltage drop issues with lower voltages.
Rela...
