Which microcontrollers do boards using the SIM808 use?
Most are built on STM32 (3) and ESP8266 (1).
How big is a typical board using the SIM808?
The median is 43 × 58.5 mm, and 25% are two-layer designs.
What is the most popular open source board using the SIM808?
By GitHub stars, GPS-Tracker by mohamedboubaker, with 40 stars.
Can I simulate one of these boards using the SIM808 before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
