Pin Definition
The ME26LS01 is a multi-band LoRa module based on Semtech's fourth-generation LR2021/LR2012 LoRa transceivers and the high-performance, low-power nRF54L15 host processor. It supports global ISM Sub-GHz and 2.4 GHz bands, along with BLE 6.0 and S-band satellite connectivity. With a compact form factor and only 5.9 mA receive current, the module delivers up to +22 dBm transmit power in the LoRa Sub-GHz band and up to +12 dBm at 2.4 GHz and S-band. Receive sensitivity can reach as low as -141 dBm. The ME26LS01 complies with the physical-layer requirements of the LoRaWAN® specification and supports FLRC and LR-FHSS, making it suitable for long-range LoRa® networking, LoRaWAN, Wi-SUN, and satellite communication applications.
