ExpressLRS Transmitters and Receivers

Happymodel ES24TX and EX900TX radio transmitter modules

These are the first ExpressLRS transmitters in the market manufactured by Happymodel. ES24TX is 2.4GHz band ExpressLRS transmitter and ES900TX is for 900MHz band. ES900TX module is capable up to 1W of the output power and comes with a 2006 sized cooling Fan, which turns on automatically when the TX power is 250mW and more. The ES24TX module is capable of outputting up to 250mW of the RF power.

Downsides – USB connector is internal and you need to open the case to access it.

HGLRC Hermes 2400TX ExpressLRS transmitter module

HGLRC Hermes 2400TX is the 2.4GHz band ExpressLRS transmitter module. Fits the standard JR module bay. Comes with the simple dipole t-style antenna. Module has USB Type-C socket for firmware updates and XT30 socket for external power supply (up to 17 volts or 4S battery), which is absolutely not needed in my opinion.

The first batches have been known to have short Wi-Fi range, due to the missing internal antenna on the PCB.

Another issue is the HLGRC failed to implement the USB reset circuit correctly.  You have to hold down the boot button there before you plug the module with the USB cable. You can access the button from the hole in the back of the case (which is super inconvenient).

ExpressLRS Receivers

Happymodel ES900RX (900MHz) and PP, EP1, EP2 (2.4GHz) receivers

ES900RX is the updated version of the ES915RX, the ExpressLRS receiver for 900 MHz band. Happymodel changed the main MCU from STM to the ESP8285, and now it has Wi-Fi upgrade capability.

PP, EP1 and EP2 2.4GHz ExpressLRS receivers were also the first 2.4GHz RX in the market. And they are still the most popular ones.

PP receiver has STM MCU and is not capable of the Wi-Fi update. The EP1 and EP2 receivers are ESP8285 MCU based and can be updated via Wi-Fi connection.

PP and EP2 receivers have unique ceramic antenna on board. They are the smallest Long Range receivers by size and weight including the antenna. ExpressLRS range is so great, that small ceramic antenna is enough to have stable decent range (several kilometers).

BetaFPV Lite 2.4GHz ExpressLRS receiver

The smallest ExpressLRS receivers in the market.

BetaFPV Lite receiver with “Tower” type SMD antenna.

BetaFPV Lite receiver with “Flat” type SMD antenna.

BetaFPV ELRS Lite receiver with “Tower” and “Flat” antenna comparison table:

	Tower Antenna	Flat Antenna
Weight	0.47g	0.53g
Size	10mm*10mm*6mm	11mm*10mm*3mm
Gain	3.3dBi	3.2dBi
Radio Efficiency	>70%	>80%
Return Loss	<-7	<-7
Range (TX 100mW 150Hz)	About 600m	About 600m (?)

Both “Tower” and “Flat” antennas have almost the same performance in gain, but the efficiency for “flat” antenna is better than “tower” antenna. However this is only the specs on the paper. In the reality the tower antenna performs better and the range is greater. Need to be noted that receiver with the “flat” type antenna has the LED on the top side of the PCB for the better visibility.

Antennas

BetaFPV Moxon an Loop antennas

BetaFPV Moxon is directional and Loop is omnidirectional antenna.

Moxon antenna is a directional antenna that focuses RF energy in a required direction. It has 5.4dBi gain and more suitable for long range flying and should be pointed towards the aircraft.

Loop antenna is an omnidirectional antenna that radiates and receives the RF energy equally, providing a 360-degree radiation pattern that allows connectivity in all horizontal directions. It has lower gain of 2.3dBi, but more equal radiation compared to the Moxon antenna. More suitable for freestyling and closer flying.

BetaFPV Moxon antenna is directional to the front. Below is the antenna 3D radiation pattern image.

BetaFPV Loop antenna is omnidirectional with a 360-degree horizontal radiation pattern. Below is the antenna 3D radiation pattern image.
