Prototype boards for ESP8266, ESP32 and ESP32-S2 modules

This is a prototype board for use with ESP8266, ESP32 and ESP32-S2 modules. The board is divided into areas that can be cut and then put together to build advanced IoT prototypes. After cutting as shown in the picture, you can start assembling the IoT device. The power supply can use a 5-12V power supply with or without integrated 3v3 LDO (in the picture you can see I used two 5V power supplies.) If the power supply does not have an integrated 3v3 LDO, then you can install a baseboard. Power Input: As you can see in my pictures, I am using KF128-3P and KF128-2P screw terminal connectors for the power input and relay output. The pins are spaced 5.08 mm apart. However, there's nothing stopping you from soldering the wire directly. You can also add more solder to the trace to allow more current flow. Relays: You can choose from two types of relays and can use up to three at the same time.
