This Micro TX is designed by Happymodel and based on the open source- ExpressLRS which is a very popular low latency and high re-flashed rate RF module for RC Airplane and FPV Racing. Its main hardware architecture is ESP32, ESP8285 and SX1280 RF chip. The ES24TX module is a complete solution which is already pre-load the Expresslrs firmware and it’s plug and play.
Specifications: Regulatory Domain: ISM2400 MCU:ESP32(main),ESP8285(aux,as espbackpack) RF chip:SX1280IMLTRT JR standard 5pin socket Frequency Range: 2400 MHz to 2500 MHz Maximum receive refresh rate: 500Hz Minimum receiver refresh rate: 25Hz RF Output Power: 10dBm~24dBm Power supply voltage: 5v~10v Weight: 9.5gram(without antenna） Dimension: 55.5mm*39.5mm*8mm Antenna gain:1.87dBi
Since the official ExpressLRS perfect program has not been released yet, our pre-installed program is a beta version, because there are too many types of beta version programs , so you can download the out of factory firmware from Happymodel website. There are two kinds out of factory firmware of ES24TX, one is to match Happymodel PP RX receiver (program version identification code 6cb8152d) and the other is to match Happymodel EP1 and EP2 RX receivers (program version identification code aec8ad82), The default factory firmware is aec8ad82 which matching EP1 and EP2 RX
You can download the firmware from Happymodel website, and then update the firmware via connect the Wifi hot spot of the ES24TX, visit “10.0.0.1” by browser (password:expresslrs)
Works great!very happy so far. Thanks NewBee Drone!!

Move over crossfire and tracer, the king is here
Ever since my first time flying ExpressLRS I have been baffled that Frsky is still in business. ExpressLRS is dirt cheap (for what it is), OPEN SOURCE, and crazy easy to setup. Just yesterday I went for a casual flight; ExpressLRS was set to 100mw broadcast power (this thing will do 250mw), 500hz refresh rate (lowest possible latency for now), and I just slapped a vas crosshair xtreme on my goggles. I went 2km away before turning back, confirmed by the m8q gps, and my link quality only dipped from 100 to 99. Right now the record for ExpressLRS 2.4ghz is 35km at 100mw broadcast power and 150hz, the pilot didn't failsafe he just turned around because of battery life. If you still aren't convinced take a look at their github and watch some of the long range flights, it is worth it.
Not as rigid as the 1.5mm shaft version, but it's to be expected to keep them light for smaller motors. Overall very pleased with these. They run very smooth. Haven't had a crash yet, so I can't give input on durability, but I'd imagine they'd be as good as any other. Would buy again.
