Ai-Thinker Ra-08H LoRaWAN Module

Description

Ai-Thinker Ra-08H LoRaWAN Module The Ai-Thinker Ra-08H LoRaWAN Module is an advanced solution designed for long-range, low-power wireless communication, tailored specifically for Internet of Things (IoT) applications. Built around the ASR6601 system-on-chip, this module integrates high-performance RF transceivers, modems, and a 32-bit RISC microcontroller unit based on an ARM Cortex-M4 core operating at 48MHz. This powerful combination ensures robust processing capabilities, making the Ra-08H an ideal choice for developing sophisticated IoT devices that require reliable, long-distance communication. Features: Adopt SMD-18 package. Support frequency: 803MHz ~930MHz. Working voltage is 3.3V, theoretical maximum transmit power: +22dBm. High sensitivity: -138dBm @125Kz SF12. Support spread spectrum factor: SF5/SF6/SF7/SF8/SF9/SF10/SF11/SF12. Embedded memory, 128KB FLASH,16KB SRAM. Support LoRa/(G)FSK/BPSK/(G)MSK modulation. Antenna interface is compatible with stamp holes / circular holes and IPEX, etc., support more option selection. Support multiple sleep modes: depth sleep current is low to 0.9uA.
