LoRaWAN Module with built-in MCU (LM502 22dBm)

The LM502 LoRaWAN module is a general LoRa Wireless Communication module. It includes an integrated LoRa Radio Transceiver, SX1262 LoRa Modem and a 32-Bit RISC MCU CY8C4147AXI-S445 from Cypress. The MCU uses the ARM Cortex M0+, with a 48MHz operation frequency. The LoRa Radio Transceiver has continuous frequency coverage from 150MHz to 960MHz. The LoRa Modem supports LoRa modulation for LPWAN use cases and (G)FSK modulation for legacy use cases.

The LM502 uses the newest LoRa Modem SX1262 providing high transmission power for ultra long range, ultra low power communication for LPWAN applications.

This LoRaWAN module can achieve a high sensitivity of over -140dBm and the maximum transmission power is higher than +21dBm. Therefore it is suitable for use in long range LPWAN, and has high efficiency.

The LM502 comes with ready to use LoRaWAN Modem software. Developers only need to use AT Commands to control the module so it can join the LoRaWAN network. The LM502 also includes programmable and reconfigurable analogue and digital blocks with flexible automatic routing. Developers can use the rich IO’s to connect to their sensors and provide a low cost/low power consumption/small size LoRaWAN End Node solution.

The LM502 demo board is a breakout board with LM502 pre-loaded. The demo board provides a rapid way for users to evaluate the features of the LM502. In addition the demo board can be powered by 12v DC or USB port.  The USB port of the LM502 demo kit will be shown as one program port and one CDC port in the computer, the program port is for flash firmware and CDC port is for serial access to LM502.
