This repo contains published hardware information for the AnyLeaf ELRS receivers. It contains schematics, KiCad schematic and PCB layout files, and production files (Gerbers, drill files, bill of materials (BOM), and pick+place files).

PCB antenna for Wifi and u.fl connector for RF. Connect the serial adapter to GND, TX, RX, and the appropriate 3V3 or 5V. Quite some serial adapters have TX and RX swapped, mislabeled, or both 😸. Please double-check!

Supports ELRS Diversity, with connections to 2 antennas via a multiplexer. Compared to our true diversity Rx, this receiver uses a single radio and PA/LNA, with a multiplixer that switches antennas based on signal strength.

ExpressLRS offers many different antenna types, with dipoles and ceramic antennas (see SMD Antennas) being the most common types of reciever antennas. In terms of range: Ceramic antenna < Mini Dipole ("Minimortal-T" style) < sleeved dipole < Half-wave Dipole.

“Any ELRS 2.4Ghz receivers can work with any ELRS 2.4Ghz TX Modules, from any manufacturer and even the DIY ones. This is as long as they have the same binding phrase and configuration options (Regulatory Domain, Performance Options and Extra Data).”

Very Tiny 2.4GHz eLRS Module to fit into the Frsky Xlite or other radio hand set.

ELRS receiver with an SX1280/1281 and 5 PWM outputs, based on the ESP8285.

The Axisflying ELRS Receiver Antenna is based on the ExpressLRS project, an open-source RC link for RC applications. Featuring a 2.4Ghz frequency, this receiver connects well with the Axisflying ELRS Receiver.

Mar 7, 2024 · The gain of the V1.1 flat antenna is technically lower than the boxy one, but by such a small amount that you shouldn't notice the difference. It's also a fraction of a gram heavier if you're trying to build the lightest of tinywhoops, but the benefit is that it …
