Slightly better than expected, worked perfectly
For ICH ESPHome Relay Module
From the photos I had expected that only one of the GPIO header pin blocks would be pre-soldered, but in fact they both were along with the UART headers - very helpful!
Powered on, connect to the access point and a web page is automatically launched. Enter your SSID, device reboots and is online. Go to the IP address it has on my LAN, upload my EspHome compiled binary through the device web page, click Update and it's done. My custom Esphome configuration running on it without ever having to connect a USB-UART converter. Nice! A great little board that I'm going to use with Wiegand RFID readers and an electric door strike lock.
