## About WIFI
## About Board Versions

Circuitpython builds after 8.0.0-beta6 target the v2.1 revision of this board. V1.0 had a design flaw
in the antenna circuitry which cannot be compensated for in software. V2.1 replaces the PCB trace antenna
with a small ceramic antenna and the status LED on GPIO7 is replaced by a WS2812B RGB addressable LED.

Using 8.0.0-beta6 or earlier builds on a v2.1 board or post-8.0.0-beta6 builds on a 1.0 board will not result in proper
status LED operation.

V1.0 boards need set WIFI Tx Power to 8.5dBm in order to use WIFI.

You need set WIFI Tx Power to 8.5dBm to use WIFI.
`wifi.radio.tx_power = 8.5`
