README
README.mdESP32_Low_Power_Development_Board
Simple ESP32 development board specifically designed for low power project.
- This PCB doesn't have on-board USB to TTL and any LED light. It allows to accurately measure current consumption of your low power IoT project.
- Each I/O has 2 pin headers, one for connecting to peripherals and one for troubleshooting purpose (Logic analyzer, oscilloscope, etc).
- Clearance and creepage minimum 0.2mm (IPC-2221A).
- Boot and reset button.
