I ordered an ESP32 module from Ebay:
The pinout for the board is shown here:
WeMos ESP32 Pinout
This module is packaged as WeMos compatible board. I’ve used the Wemos ESP8266 modules previously and they provide a neat stackable package with a few pre-built modules for SD card readers, OLED displays, etc.
Plugging the module in and viewing the serial data on boot at 115200 baud shows that ‘Happy Buddha Trading’ appear to install some test software on the device. It doesn’t seem to create a Wifi hotspot, but it does activate the Bluetooth module, which I can view from a phone but not pair to.
