The Ai-Thinker Ra-01SH is a compact LoRa wireless communication module based on the Semtech SX1262 transceiver. It supports long-distance spread-spectrum communication in the 803MHz to 930MHz range and is designed for embedded IoT hardware that needs high sensitivity, strong anti-interference performance, and low-power wireless connectivity.

The official Ra-01SH specification lists LoRa, FSK, GFSK, MSK, GMSK, and OOK modulation support, SPI half-duplex communication, up to +22dBm output power, and receive sensitivity down to -140dBm. This SKU uses an IPEX antenna connector, making it suitable for devices that require external antenna placement and enclosure-level RF validation.

Integration Notes & Hardware Guidance

Power Supply Use a stable 3.3V rail within the 2.7V to 3.6V range and reserve more than 200mA supply capacity.
Ripple Control Prefer clean LDO power where possible; if DC-DC is used, keep ripple low and reserve dynamic response capacitance.
SPI Routing Keep SCK, MISO, MOSI, NSS, reset, BUSY, and DIO lines short and away from noisy switching-power nodes.
Antenna Connection Use a matched IPEX antenna for the selected frequency band and verify antenna placement inside the final enclosure.
Regional Frequency Configure frequency, bandwidth, spreading factor, and output power according to local radio regulations.
No-Load Protection Do not operate the RF output without a suitable antenna or 50 load during debugging.
Host Firmware Ensure the host MCU handles SX1262 BUSY, TXEN, RXEN, reset, DIO events, and packet configuration correctly.
ESD Handling Treat the module as an electrostatic-sensitive RF device during soldering, test, and assembly.
Range Validation Test the antenna, enclosure, link budget, and RF settings in the final product form before deployment.
