Lilygo T-Beam

I use the T-Beam with SoftRF. This came installed. A description of this is on the SoftRF wiki.

To update the firmware,

• download the latest firmware
• Connect to the T-Beam using WiFi
• Web browser to http://192.168.1.1
• Select "upgrade"
• Select firmware file to upload
• Check and reset all settings

T-Beam Supreme

The new version is a similar form factor but different in all the details.
