# jeep-canbus: decoding the Jeep Grand Cherokee CAN-B bus

> jeep-canbus documents byte-level meanings of observed CAN-B frames in a Jeep Grand Cherokee WH. The repository combines capture-based ID maps with an ATmega328 radio gateway and an ESP32 dashboard that receives and interprets vehicle data.
