LoRa radio modules for IoT and smart metering: AI50H & ST50HE
The two LoRa modules Ai50H and ST50HE from the Korean LoRa specialist AcSiP are particularly flexible when it comes to IoT and smart metering applications. The AI50H with ultra-narrowband modulation impresses with its duality - it masters both LoRa and Sigfox technology.

All-rounder for IoT applications: AI50H
The extremely compact AI50H module measures just 20mm x 20mm x 1.95mm and fits both LoRa and Sigfox. The module can serve both technologies and is therefore particularly flexible to use. The AI50H is driven by a Cortex M4 32bit RISC controller and a memory of 256K Flash with 64K RAM. It has numerous interfaces, such as 2 DMA, 2 USART, 1 LPUART, 2 SPI, 3 I2C and is also very powerful with an extremely low power consumption ( >1.3uA). The VBAT mode with RTC and 20*32 bytes backup registers as well as the integrated battery voltage monitoring complete the profile of the module. Likewise the approval of the safety certification: CE/FCC/TELEC/NCC.
The smaller alternative: ST50HE
With a very similar performance level, the even smaller ST50HE offers itself as a price-sensitive alternative. The ST50HE also combines LoRa and Sigfox in one module. It is very similar to the AI50H, only the output power of +14dBm is lower than the "big" AI50H. Significant is definitely the size of the ST50HE - it is smaller and has a very compact form factor of only 12mm x12mm x1.2mm.
The ST50HE is powered by an ARM Cortex®-M4 MCU with LoRa modulation and offers long-range communication in a wide range of applications. It has various interfaces such as: 2x DMA, 2x USART, 1x LPUART, 3x I2C, 2x SPI and offers a programmable bit rate of up to 300kbps. The radio module impresses with its very low susceptibility to interference and significantly reduced power consumption.
