LTE-M/NB-IoT Dual Mode Module/Multi Band
TPM541 Series - LTE-M/NB-IoT Dual Mode Module/Multi Band

TPM541 is high-performance, multi-band dual mode LTE-M/NB-IoT module with extremely low power consumption. The extremely compact form factor of 13.4 × 14.6 × 1.85mm profile makes it perfectly suitable for size sensitive applications. TPM541 provides abundant external interfaces and protocol stacks, as well embedded GNSS for positioning application.

TPM541 adopts surface mounted technology, making it an ideal solution for durable and rugged designs. The low profile and small size of LGA package allow TPM541 to be easily embedded into space-constrained applications and provide reliable connectivity with applications.

Due to compact form factor, ultra-low power consumption and extended temperature range, TPM541 is a best choice for a wide range of IoT applications, ranging from smart metering, bike sharing, smart wearables, smart parking, smart city, security and asset tracking to home appliances, agricultural and environmental monitoring, etc. Additionally, TPM541’s embedded MCU provides benefit to those cost and space-sensitive application via saving external processor.
