Raspberry Pi 4B
The Raspberry Pi 4 Model B is the fourth-generation flagship single-board computer from the Raspberry Pi Foundation. Both the RAK8622 and RAK8623 use the 2 GB RAM version.
RAK6421
RAK6421 is a powerful Raspberry Pi HAT that lets you connect WisBlock modules directly to any Pi. It is compatible with the HAT+ specification by using an independent EEPROM for metadata and device tree information.
RAK12501
RAK12501 is a GNSS module based on the Quectel L76K.
RAK13300
RAK13300 is based on the Semtech SX1262 module for LoRa and LoRaWAN applications.
