Sercomm introduces compact cellular IoT module with Nordic SoC for low-power applications

Network technology specialist Sercomm has introduced a new cellular IoT module based on Nordic Semiconductor’s nRF9151 reference design.

The module named TPM530M integrates Nordic’s nRF9120 System-on-Chip (SoC) along with dedicated power management and RF components, targeting applications that require reliable cellular connectivity with low power consumption.

With dimensions of just 14.55 x 14.51 x 1.85 mm, the TPM530M is particularly suitable for space-constrained use cases – including smart metering, bike sharing, wearables, smart city solutions, security technology, asset tracking, and environmental monitoring. The module supports LTE-M and NB-IoT across multiple frequency bands and features GPS as well as an extended operating temperature range from -40 to +85 °C.

For developers, the module offers a 64 MHz Arm® Cortex®-M33 application processor with 1 MB of non-volatile memory and 256 KB of RAM. It also provides interfaces such as SPI, UART, I2C, PWM, ADC, and 32 GPIOs. Power consumption in Power Saving Mode (PSM) with memory retention is reduced to as low as 2.7 µA; in eDRX mode, average consumption is around 6 µA for LTE-M and 9 µA for NB-IoT.

Sercomm also relies on Nordic’s nRF Connect SDK, which supports developers in building LTE-M and NB-IoT products. Pricing details have not yet been announced by Sercomm and Nordic; availability is planned through Nordic’s distributors.
