QK Nano receiver is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.
These are based on ESP8285 as mcu, which provides you the option to flash via wifi, via uart or via betaflight passthrough.
