There are many ESP32 boards with a SubGHz radio. But they are either ESP32 with a SX127x or ESP32S3 with a SX126x.
A lot of them come with built in battery support.
The next problem with this project is the used radio: The SX12xx series from Semtech is good but lacks a lot of features like the CC1101 as used in the Flipper Zero.
I really like the idea of using an ESP32 but the choice of the used radio is a bit akward.
- andreock 2y agowhy do you say this? I find SX1276 a perfect replacement for CC1101( that have problems with shared SPI bus). Also SX1276 support LoRa and have a wider frequency range than CC1101.
- atVelocet 2y agoThe SX127x doesn’t have the same features and CC1101 has way more options to fine tune any aspect of the radio.
