STM32WLE5 inside Module AcSiP AI50H

STM32WLE5 inside Module AcSiP AI50H

For several safety certifications approval, AcSiP design a total module with matching antenna pattern to achieve promotion of wireless LPWAN module in world wide. AI50H has passed CE,FCC,TELEC and NCC and it integrates ARM Coretex®-M4 (32-bit RISC core operating at a 48MHz frequency) MCU with LoRa modulation. It offers an ultra-long-range spectrum communication and high interference immunity simultaneously minimizing power consumption.

The AI50H can achieve a sensitivity under -136 dBm. It has high sensitivity and combined with the integrated +20 dBm power amplifier yields. The industry-leading link makes it optimal for any low data rate application. LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques. Solving traditional issues between range, interference immunity, and energy consumption.

The AI50H stamping type module has embedded ST50H inside and integrated multi-antenna pattern to pass major safety certifications in the world. AcSiP will help clients to meet the local safety regulation while their product of LPWAN application integrated AI50H. Those resources are available for developer and check it further to sales of AcSiP if need.
