Esp32-loradv transceiver: common questions

What microcontroller does the Esp32-loradv transceiver use?

The Esp32-loradv transceiver is built around the ESP32, from the ESP32 family.

How big is the Esp32-loradv transceiver PCB?

The Esp32-loradv transceiver measures 40 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-loradv transceiver?

30 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-loradv transceiver design files?

From the alonsoo-rodriguez/esp32-loradv-transceiver repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32-loradv transceiver design in my own project?

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

Can I test firmware for the Esp32-loradv transceiver 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.
