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.

What makes it special?

Very thin PCB for small but complex enough projects to require an ESP32 with full size flash (16MB)

International shipping

I have no problems shipping to all destinations, but believe me it's anti-economical. It would be cheaper to order a small amount (5) to a PCB fab (I can share Gerber, BOM and Pick and Place) geographically "closer" to your place. The smallest package outbound from US is about $30.
