Adafruit Feather RP2040 RFM69 Packet Radio - 868 or 915MHz - RadioFruit and STEMMA QT Brand_TJD Onboard high precision RTC chip

Onboard high precision RTC chip DS3231 with backup battery

so it's possible to add more LEDs onto the chain that's on the front of the board

There's even a black ribbon bookmark/page marker to keep your place

The battery can be charged with a +5V power supply with the Raspberry Pi board either switched on or off

It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly reasonable 52% when it feels more like 77%

Adafruit Feather RP2040 RFM69 Packet Radio - 868 or 915MHz - RadioFruit and STEMMA QT Brand_TJD Onboard high precision RTC chipThis is the Adafruit Feather RP2040 RFM69 Packet Radio (868 or 915 MHz). We call these RadioFruits, our take on a microcontroller with packet radio transceiver with built in USB and battery charging. It's an Adafruit Feather RP2040 with an RFM69HCW 900MHz radio module cooked in! Great for making wireless networks that are more flexible than Bluetooth LE and without the high power requirements of WiFi. Feather is the development board specification
