2.4 GHz ELRS Module Design

Descripción de la oferta
I need a complete ExpressLRS-based 2.4 GHz solution designed from scratch, covering both the transmitter module and the matching receiver unit. This is a brand-new product, so nothing can be copied from an existing board. Scope of work • Electronic design: create schematics, select RF front-end, MCU, power stage, and filtering suitable for reliable 2.4 GHz operation under ELRS requirements. • PCB layout: optimise for low noise, clean RF paths, correct impedance, and size/weight appropriate for FPV use. • Firmware hooks: prepare pin mapping and reference code so ELRS firmware can be flashed and tested right away. Full ELRS compliance is mandatory. • Supporting files: BOM with readily available parts, production-ready Gerbers, and a brief bring-up guide. Key points • Deliver both transmitter and receiver boards. • Prior RF work or proven ELRS experience is highly valued. • I’m looking to move fast, so please outline realistic turnaround times for schematic, layout, and first-article files. • I will prototype in-house; rapid assistance during initial bring-up is expected. Dimensions: Small 20*15-20 Weight: 0.7 g (RX only) Chips: ESP8285, SX1281 Crystal Oscillator: TCXO Frequency Band: 2.4 GHz ISM Refresh Rate: 25 Hz – 1000 Hz Input Voltage: 5V Antenna Connector: IPEX1 Telemetry power 100mw 2 layer pcb if possible. If you can take this from concept to manufacturing-ready files quickly and confidently, I’m eager to get started.
