🪶 Introducing the Happymodel ELRS Micro ES900RX/ES900TX Combo Kit: a cutting-edge solution for enthusiasts seeking unparalleled range and performance in their RC FPV long-range racing drones. Operating within the 915MHz or 868MHz frequency bands, this dynamic duo of transmitter and receiver offers a sophisticated linkage tailored for serious drone pilots.
🔧 Key Features:
- High-Performance Components: The ES900TX module is powered by a robust ESP32 combined with an ESP8285 MCU, while the ES900RX operates on the efficient ESP8285. This combination ensures ultra-reliable and stable performance throughout your flights.
- Impressive Range and Power: The ES900TX module boasts a maximum output power of < 33dBm, enabling long-distance connectivity. The ES900RX receiver, being incredibly lightweight at only 0.6g (excluding antenna), is designed for miniature drones like Whoops and Toothpicks.
- Easy Installation: Designed for seamless integration with a wide array of Opentx remote controls, including popular models like the Radiomaster TX16S and Jumper T series, this setup is practically plug-and-play.
- Enhanced Cooling Mechanism: The newly designed ES900TX now includes a custom cooling module equipped with a 2006 cooling fan to ensure optimal performance, particularly when running at high power. This fan activates automatically when the transmission module reaches 250mW, maintaining system stability.
🕊️ Dimensions and Specifications:
- ES900RX Receiver: Dimensions: 12mm x 12mm x 3mm, Weight: 0.60 grams (antenna not included), Input Voltage: 5V, Operation Current: ~100mA, RF Frequency: 915MHz/868MHz, Telemetry Output Power: <17dBm.
- ES900TX Module: Dimensions: 55mm x 39mm x 11mm, Weight: 9.2 grams (TX module only), Input Voltage: 5V-13V (recommended range 5V-9V), RF Frequency: 915MHz/868MHz, Maximum Output Power: <33dBm, Antenna Connector: SMA.
📎 Frequency Synchronization:
🧰 Setting up the ES900RX receiver for frequency alignment is straightforward:
- Power on the ES900RX; after the LED goes out, turn it off immediately. Repeat this step. On the third power-up, the LED will double flash, indicating it has entered frequency synchronization mode.
- Connect the ES900TX or ES915TX high-frequency module, select the CRSF protocol on your remote; navigate to the ELRS option and proceed to BIND. Once successfully matched, the LED will initially turn off, then slowly flash, and eventually remain lit.
