PRODUCT DESCRIPTION Anxinke LoRa series modules (Ra-01SH) are designed and developed by Anxinke Technology. This module is used for ultra-long-distance spread-spectrum communication. Its radio chip SX1262 mainly uses LoRa remote modem for ultra-long-distance spread-spectrum communication. It has strong anti-interference and can minimize current consumption. With SEMTECH's LoRa patented modulation technology, SX1262 has a high sensitivity of over -148dBm, a power output of +22dBm, a long transmission distance and high reliability. At the same time, compared to traditional modulation technology, LoRa modulation technology also has obvious advantages in anti-blocking and selection, which solves the problem of distance, anti-interference and power consumption that traditional design solutions cannot simultaneously take into account. Application areas are used in automatic meter reading, home building automation, security systems, and remote irrigation systems. Features LoRa modem 140mA Support FSK, GFSK, MSK, GMSK, LoRa and OOK modulation methods Support frequency band 903MHz~927MHz Working voltage is 3.3V, maximum output is +22dBm, maximum working current is Low power consumption characteristics in receiving state, the minimum receiving current is 4.2 mA, standby current is 1.6mA High sensitivity: as low as -140dBm Small volume dual row stamp hole patch package The module adopts SPI interface, half-duplex communication, with CRC, up to 256-byte packet engine Copyright 2020 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved 5 17 Ra-01SH Specification V1.1 Compatible with half-hole pads/through-hole pads (need to solder the antenna)/IPEX socket Main parameters Model Ra-01SH Package SMD16 Size 17*16*3.2(0.2)MM List 1 Main parameter description Antenna Spectrum range Operating temperature Storage environment Power supply 903MHz~927MHz

SCHEMATIC DIAGRAM Copyright 2020 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved 12 17 6.DESIGN GUIDE 1Application circuit Ra-01SH Specification V1.1 2Recommended module package design size Note: This is the Ra-01SH module package drawing. It is recommended to design the PCB board according to this drawing so that the module can work normally on the PCB board; and when designing the pads, pay attention to the design of the pads on the PCB. The group corresponding to the pad shrinks and offsets, and the PCB pad expands from the module pad without affecting the use of the module. 3Antenna installation Copyright 2020 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved 13 17 Ra-01SH Specification V1.1 1Ra-01SH needs to be used for soldering antennas, and the module is compatible with half-hole pads and round-hole pads. 2In order to achieve the best effect of the antenna, the antenna assembly location should be far away from the metal parts. 4Power supply 1Recommended 3.3V voltage, peak current recommended above 200mA 2It is recommended to use LDO for power supply; if DC-DC is used, the ripple is recommended to be controlled within 30mV. 3It is recommended to reserve the position of the dynamic response capacitor for the DC-DC power supply circuit, which can optimize the output ripple when the load changes greatly. 4It is recommended to add ESD devices to the 3.3V power interface. Copyright 2020 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved 14 17 Ra-01SH Specification V1.1 5Use of GPIO port 1There are some GPIO ports on the periphery of the module. If you need to use it, it is recommended to connect a 10-100 ohm resistor in series with the IO port. This can suppress overshoot and make the levels on both sides more stable. It is helpful for EMI and ESD. 2For the pull-up and pull-down of special IO ports, please refer to the instructions in the specification, which will affect the startup configuration of the module. 3The IO port of the module is 3.3V. If the main control and the IO level of the module do not match, a level conversion circuit needs to be added. 4If the IO port is directly connected to a peripheral interface or terminal such as a header, it is recommended to reserve an ESD device near the terminal of the IO trace.
