Programmable wifi board with adc inputs?

Where is PurpleAir sourcing their programmable wifi board with adc inputs.
We had a lightning strike nearby and we think the board may have fried.
The BME280 is Bosch Sensortec.
The PMS-5003 is Plantower.
But what about the wifi board?

It’s a custom board. The chip (which includes the WiFi) is an ESP8266 (see more here).

We support the right to repair, so we’re happy to sell you any components you need. Just know that a new board will come with a new sensor “identity,” so you’ll need to set it up as a new device if you replace the mainboard.

Feel free to email us at contact@purpleair.com to set up component orders. We’re also happy to help you troubleshoot.
