Features: The BETAFPV receiver is base on the ExpressLRS project, an open source link for applications. The ExpressLRS achieves better link performances in terms of speed, latency, and ranges.This makes ExpressLRS one of the faster available while still providing remote performances. ExpressLRS is base on Semtech LoraSX127x or SX1280 hardware and is used for RXandTX, respectively. It aim to achieve better link performances in terms of speed, latency, and ranges. At 900MHz, it supportsup to 200Hz Rate. At 2.4GHz, customOpenTX builds currently support an astonishing 500Hz. This makes ExpressLRS availableOne of the faster link while still providing remote performances Specifications: Material:PCB Optional:915MHz ELRS Receiver,2.4G ELRS Receiver; Note: Please allow 1-2cm errors due to manual measurement,please make sure that you do not mind before you order.
