The SP24S 2.4GHz ELRS series receiver is based on the open-source architecture ExpressLRS. The receiver uses an ESP8285 MCU, so you can upgrade the firmware through WIFI. As long as the receiver is powered on and the remote control is turned off, you can find ExpressLRS and connect to this hotspot through a computer or mobile phone. The connection password is expresslrs and it will automatically enter the upgrade page. If you don’t have one, you can manually visit to upload the receiver firmware. Of course, you can upgrade the firmware with a flight controller and external USB. With the built-in ceramic antenna, you'll never have to worry about it falling off.
