ST50H 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 ST50H can achieve a sensitivity under -136 dBm. It has high sensitivity and combined with the integrated +22 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 power consumption.

AcSiP has a stronger support chain in technical service which included FAE,HW,SW resource involved.
- SiP Module
Those Tabpages of ‘Specification’, ‘HDK’ could be refered to know this product further well.
- Validation & Certification
AcSiP has accumulated lots of experience in wireless communication and provide solution of RF design and protocol survey to help clients’ products meet local regulation and join global ecosystem well. From project deveoping to product getting certification approval, even know-how in deployment stage,we has collected useful data here for user reference.
We have developed sigfox support resource to service clients for another LPWAN ecosystem.
AcSiP provide kinds of software for ST50X series product,ST50H/ST50HE/AI50H,to develop IoT relevant applications.
There are main LoRa examples within SDK show behind.
3)Training & E-Service
FAE is first layer to handle all technical events or service demand. Clients and customers could ask help via familiar channel or sales host to get positive response efficiency or check out online E-Service window finding the relevant resource as well. AcSiP has prepared those data for products in technical support or training courses.
The ST50H integrates ARM Coretex®-M4 (32-bit RISC core operating at a 48MHz frequency) MCU with LoRa modulation that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
The ST50H can achieve a sensitivity of over -136 dBm. The high sensitivity combined with the integrated +22 dBm power amplifier yields industry leading link budget making it optimal for any low data rate application requiring range or robustness. LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.
|Part Number||Frequency Range||Spreading Factor||Bandwidth||Effective Bitrate||Est. Sensitivity|
|ST50H||779~928MHz||5~12||7.8~500KHz||LoRa BR: 0.013~17.4bps||-136dBm|
|Kb/s(G)FSK BR:0.6~300kb/s||@125kHz, SF12|
The SiP module will conform to the following pin map (Top View) and recommand footprint (mm)
The EK-ST50H board provides an affordable way for user to try out LPWAN IoT applications or new concepts evaluation. It also compliance with STM32WL Necleo-64 board to support ARDUINO Uno V3 connectivity support and the ST morpho headers.
User can download firmware built from SDK via ST-Link to test software flow and debug error according to log shown on termanal tool.
►CE/FCC Certification will be ready on 202108
►TELEC/NCC Certification will be approval by AI50H
|EK-ST50H||1||Micro USB for Power source and RS232 I/F|
|Antenna (option)||1||High band for EU868, US915, AS923|
Developers could refer to behind figure for essential resource layout then has a survey and implement in their product cases
|User can configure RS232 terminal tool to control EK-ST50H board for SW validation and application development|
►SMA connector-Antenna or RF instrument
►Peripheral pins-App implement
Application note have showed essential RF layout info for developer reference and make certification approval easier.
AcSiP provide HW/SW relevant engineer service for clients in module design phase and its technical resource has shown on each individual tabpage also.Additionally, we have provided those design review serive before the engineer sample came out even debugged for revised one and the clent can ask our sales window, E-Service for this help.
