What is it?

This is an ESP32 "dev" module without a built-in programmer so that it can be used in small projects. It has:

16MB of flash RAM on board.
battery charging circuitry
low quiescence LDO
built-in green LED (pin 2)
voltage divider to read the battery voltage (pin 35)
GPIO0 and RESET buttons
Serial TX / RX line exposed on the microUSB port

Why did you make it?

I wanted a module that I could use with small prototypes that could be shipped to a 3rd party without the risk of easy reverse engineering. On the other hand it requires a separate programmer (any USB-UART based ones should work). Also upped the flash storage to the maximum available. Thanks to built-in BLE/BT Classic and Wi-Fi, this has revealed to be a tool of multiple trades.
