GroED: common questions

What microcontroller does the GroED use?

The GroED is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.

How big is the GroED PCB?

The GroED measures 98.1 × 98.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the GroED?

257 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the GroED design files?

From the BB-KING777/Agri_iot_pcbs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the GroED design in my own project?

The repository has no license, so all rights stay with BB-KING777. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the GroED without the hardware?

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