Core1121 sub-GHz, S-Band, and 2.4GHz LoRa module features through holes and castellated edges
The Waveshare Core1121 is a compact, multi-band LoRa module based on the Semtech LR1121 transceiver with support for Sub-GHz (150–960MHz), S-band (1.9–2.1GHz), and 2.4GHz ISM bands, and exposing GPIOs through both through and castellated holes. Key features include support for LoRa, (G)FSK, and LR-FHSS modulation schemes, AES-128 encryption, and compatibility with the SX126X/SX127X series for easy migration. We just noted Seeed Studio’s Wio-LR1121 last week with a very similar, yet more compact design with only castellated holes, and before that, the LR1121 was used in the MuRata Type-2GT module and a LILYGO module as an option for the T-Eth Elite board. Core1121 specifications: RF Transceiver – Semtech LR1121 Frequency bands Sub-GHz (150MHz ~ 960MHz), Different varieties for Europe, North America, Oceania, Asia S-band (1.9GHz ~ 2.1GHz) 2.4GHz ISM frequency bands Output Power Up to 22dBm @ 868/915 MHz (Sub-GHz) Up to 13dBm max @ 2.4GHz Receiver Sensitivity -127dBm @ Sub-GHz, SF7, CR4/5, […]
