FrSky receivers with PPM, CPPM and SBUS: XSR and D8
Today, I will review two FrSky receivers, the mini D8 and the XSR ACCST. While the Micro Frsky D8 features PPM and SBUS, the FrSky XSR has S-Bus CPPM output.
For those who are new in the field, let me say a few words about radio receivers. Their main function is to interlink wirelessly the flight controller with the transmitter...
Ultra Durable water-proof ELRS receiver from DarwinFPV
Regarding FPV drone parts that are waterproof or water-resistant, it's important to note that, while some components like this DarwinFPV Cement ELRS receiver might have a certain level of protection against moisture, truly waterproof FPV components are relatively rare due to the nature of the electronic components involved. Water resistance can be particularly useful if you plan to fly...
RadioMaster RP4TD: GEMINI ready ELRS diversity RX
RadioMaster is a company that, from the beginning, started to offer ExpressLRS-compatible devices, including transmitters and receivers. Their new RP4TD diversity ELRS RX module comes with a dual-antenna system for improved range and penetration. When paired with TX modules such as the BetaFPV SuperG, you can use the ELRS Gemini mode.
To ensure improved stability, regardless of temperature, the RadioMaster...
BETAFPV radio ELRS Series (RX + TX)
BetaFPV is about to release its first radio communication system based on the ExpressLRS opensource project. 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. The BetaFPV ELRS Nano TX module will compatible with many popular remote controllers,...
RadioMaster Bandit ExpressLRS: 915MHz ELRS RX and TX
After testing so much 2.4GHZ ELRS hardware, I thought it was time to review some 915MHz equipment too. RadioMaster's Bandit series includes three TX units (RF, Micro, and NANO) and two RX modules (BR1 and BR3). In this article, we will check out the features and how to set up the Bandit Nano transmitter module and BR3 radio receiver.
ExpressLRS...
HGLRC Herme ExpressLRS: ELRS TX/RX (900MHz/2.4GHz)
After Happymodel and BetaFPV, HGLRC also announced their first ExpressLRS enabled radio system. Like its contenders, the Herme ExpressLRS also has 900Mhz and 2.4GHz versions. ExpressLRS (ELRS) is an open-source RC link for various applications, including drone communications. ELRS uses LoRa modulation with strong anti-interference technology to achieve long-range transmission with low power usage.
HGLRC claims that the Herme ExpressLRS...
BetaFPV ELRS Lite Receiver
After the ELRS Nano RX radio receiver, BetaFPV released today an even smaller ExpressLRS compatible module with a built-in antenna. The ELRS Lite Receiver measures just 10x10mm and weighs only 0.47 grams.
The tiny module is built around an ESP8285 processor and SX1280 LoRa RF CIP that provides 17mW telemetry power. In addition to the four soldering pads (GND, VCC,...
RadioMaster ELRS EP1 & EP2 Nano RX radio receivers
A few months ago, RadioMaster introduced two ExpressLRS-compatible radio receivers with their Zorro transmitter. This review will look more closely at the RadioMaster ELRS EP1 and EP2 Nano RX ELRS radio receivers.
ExpressLRS is a relatively new radio protocol that is focused on range and latency. Regarding remote drone operation, these are the two most important factors besides reliability. Being...
CYCLONE Nano 2400RX ExpressLRS radio receiver
The CYCLONE Nano2400RX ELRS receiver has a power amplifier (PA+LNA), so it has a 100mW telemetry output and better sensitivity at longer distances. It adopts the IPEX1 generation antenna base and cooperates with an external dipole T-type antenna.
The Nano 2400RX module measures just 11x18x3mm and weighs only 3 grams. It features an IPEX1 antenna plug and comes with a...
Happymodel EP1 Dual ELRS Receiver: True Diversity!
The Happymodel EP1 is the first ELRS-enabled true diversity radio receiver. It aims to provide the best range even in difficult conditions. Happymodel EP1 has two antennas and two radio modules for doubling the signal quality. In theory, "Diversity" uses at the time only one antenna by toggling to the antenna that has the strongest signal. The EP1 uses...
BetaFPV SuperD ELRS Diversity Receiver
BetaFPV's new SuperD ELRS 2.4G Diversity Radio Receiver has dual RF receiver chains with two antennas, ensuring longer and more stable flying for FPV drones and other RC flying machines. It is equipped with two T-type antennas, just like the Happymodel EP1.
The BetaFPV SuperD ELRS RX module measures 22x14mm and weighs about 1 gram without the antennas. It features...
