Sendove box: common questions
What microcontroller does the Sendove box use?
The Sendove box is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.
How many components are on the Sendove box?
50 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the Sendove box design files?
From the phongnickchinh/sendove-box repository on GitHub, which has the schematic; the links under Design files point to each one.
Can I use the Sendove box design in my own project?
The repository has no license, so all rights stay with phongnickchinh. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Sendove box without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
