Then you have to connect your PC to the WIFI Hotspot the TX module created. The TX module will enter into the WIFI mode. Select WIFI Update from the ELRS Lua script. The compiling result should be the firmware.bin file that can be uploaded via WIFI or UART. Select the firmware version, device type and flashing method.Īnd press the button. Compiling the firmwareįirst you need to compile the firmware with the ExpressLRS Configurator. For UART method you can connect the TX module directly to the PC and you don’t need the Radio for flashing the ExpressLRS firmware to TX module. For WIFI method you will need the OpenTX radio with ExpressLRS Lua script running.
2.4ghz receiver circuit how to#
There are two options how to upgrade the TX module firmware – via WIFI or via UART(USB). It has 100mW telemetry output and in theory better sensitivity (longer range).īetaFPV also sells the JR Lite to JR type (or so called Nano to Micro) adapter box. The weight of the supplied T-style antenna is 1 gram.Īnd the total weight of receiver and antenna is 1.8 grams.īetaFPV Nano receiver is the first and (so far) the only receiver with power amplifier ( PA+LNA). The weight of the bare BetaFPV Nano receiver is only 0.8 grams. There is a ceramic antenna for WIFI connectivity, the boot button and the LED on the other side of the receiver. This is the same pinout as on TBS Crossfire Nano receiver, and is recommended design pattern for all ExpressLRS receivers. You can see the standard pinout pattern R T V G (RX, TX, +V, GND) on the antenna side. You should remove it before plugging the MMCX pigtail.īetaFPV ExpressLRS Nano receiver comes with T-style dipole antenna, silicone wires, two heat shrinks and a pin header if you need to solder one. The supplied Moxon type antenna has a cover on the MMCX connector. This heatsink does the job well and the module does not overheat even on the 500mW output. It is exposed to the outside and can get pretty hot on higher power output levels.
