This device now comes with a Wi-Fi module incompatible with Tasmota
Edit 06//13/2022: Purchased from Amazon. The unit has an unsupported WB3S microcontroller. It is possible (board 21315 v1.1) to swap with an ESP-12 module but the top red/ blue LED for the WiFi connection status will not work. This LED would require input ADC0 to be able to be configured as an output. As a workaround, after cutting the trace to ADC0 and routing this trace to GPIO2 it is possible to use this LED.
