Three Rangers, One Radio Link: Buy the Bay, Not the Case
Quick Answer
The RadioMaster Ranger Micro and Nano provide the same 2.4GHz ExpressLRS radio hardware in different module-bay formats: Micro for JR-style bays, Nano for compact bays. Buy the one that physically fits your transmitter. Choose the full Ranger only if its OLED controls, two bay adapters and bundled Moxon antenna solve a real need.
The Case Is Not the Radio Link
Our catalogue makes this choice look more complicated than it is. The Ranger Micro and Ranger Nano use the same ESP32 main processor, ESP8285 backpack processor and SX1281 RF chip. Both cover 2400–2480MHz, support Wi-Fi and Bluetooth, accept 6–16.8V through XT30 and reach F1000 packet mode with a suitable EdgeTX setup.
The decision between those two is therefore mechanical, not RF. Micro fits a JR-style five-pin bay such as the TX16S or TX12 family; Nano fits compact Nano/Lite bays such as the RadioMaster Zorro. The Nano is listed at 48g with its antenna and the Micro at 50g, so choosing the wrong plug to save 2g is a bad trade.
What the Full Ranger Actually Adds
The full-size Ranger does not buy a different frequency or a faster headline packet rate. It adds a 64×128 OLED, five-way navigation, shortcut buttons, a CNC aluminium case, a three-axis accelerometer, Micro and Nano bay adapters, a CRSF cable, plus both T and directional Moxon antennas. Without an antenna it is listed at 126g, compared with 39g for Nano and 40.5g for Micro.
| Model | Best fit | Listed weight without antenna | What is different |
|---|---|---|---|
| Ranger Micro | JR-style Micro bay | 40.5g | Direct five-pin fit |
| Ranger Nano | Nano/Lite bay | 39g | Compact-bay connector |
| Ranger | Multiple radios | 126g | OLED, controls, adapters and Moxon |
What We Would Actually Buy
For one transmitter, we would buy the Micro or Nano that fits natively. They keep the radio lighter and preserve the core 2.4GHz ELRS capability. The full Ranger makes sense for a shared kit bench, mixed transmitter fleet or directional-antenna use where its adapters and front-panel controls remove friction.
Do not buy any Ranger merely because its listing says 1W. RadioMaster’s CE specification is 20dBm, and more power does not replace sound antenna placement or a healthy receiver installation. Start with the correct regulatory domain and modest output, then inspect link quality rather than treating the maximum setting as normal. Our ELRS system explanation covers bands and receiver choices; use our firmware update workflow before changing targets or versions.

FAQ
Q: Is the Ranger Micro weaker than the full Ranger?
A: Not by the published core specification. Both use the SX1281 RF chip and support the same maximum packet mode. The full Ranger’s advantage is its enclosure, interface, adapters and supplied antenna choice.
Q: Can I use F1000 immediately?
A: Only when the transmitter, EdgeTX configuration, module firmware and receiver mode support it. F1000 also needs a sufficiently fast CRSF baud rate. For general flying, choose a stable packet rate before chasing the largest number.
Q: Should I add a Ranger to a radio with internal ELRS?
A: Usually not. An external module is worthwhile when you need a compatible band, more permitted output, or specific module features. Otherwise the internal ELRS system keeps the radio simpler and lighter.
