Introduction

• Operating Voltage: AC 100~250V
• Rated Current: 10A
• USB Output 5V/4A
• Shell Material: ABS + PC
• Dimensions: L334 * W64 * H40 mm

Flashing

The hardware is based on Tuya's TYW-E2S ESP8285 WI-FI module, documented in https://docs.tuya.com/en/hardware/WiFi-module/wifi-e2s-module.html (in the same website you find documentation for TYW-E1S and TYW-E3S as well)

Unfortunately the TYM-E2S does not expose GPIO0 on the edge connector. This pin is required to be strapped to ground to put the ESP8266/85 in bootstrap mode.

There is a test pad on the back of the device which needs to be temporary shorted to ground during programming. The other required pins are all available on the edge connector on the side with VCC and GND.

Note that once the espurna firmware is onboard, updates and changes can be done with the OTA feature of the firmware without physically accessing the device again.

Usage

The switches are mapped as follows:

• Switch 1 - socket closest to the power cord
• Switch 2 - second socket
• Switch 3 - ?
• Switch 4 - socket closest to the USB connectors
• Switch 5 - powers/unpowers the USB power supply

The button does not command any of the relays, but it is active on extended/double click keypresses (reboot/reset to factory settings etc).
