Gsm iot core hw: common questions

What microcontroller does the Gsm iot core hw use?

The Gsm iot core hw is built around the STM32F405RGTx, from the STM32 family.

How big is the Gsm iot core hw PCB?

The Gsm iot core hw measures 25.4 × 64.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gsm iot core hw?

92 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gsm iot core hw design files?

From the iotmakervn/gsm-iot-core-hw repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Gsm iot core hw design in my own project?

The repository has no license, so all rights stay with iotmakervn. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Gsm iot core hw without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
