About the Beehive PCB

Beehive is an open source ESP32 PCB design by BeeHive-org, published on GitHub under the MIT license. It is a 2-layer board measuring 117.9 × 110 mm, with 48 components from 28 distinct parts.

Its main chip is the ESP32-DEVKITC-32D, from the ESP32 family. Other key parts include the MIKROE-1820, MC33269DT-3.3G and LM2596T-5. By type, the board carries 34 connectors, 5 ICs, 5 capacitors, 2 diodes, 1 inductor and 1 resistor.

Beehive: common questions

What microcontroller does the Beehive use?

The Beehive is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the Beehive PCB?

The Beehive measures 117.9 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Beehive?

48 components, from 28 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Beehive design files?

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

Can I use the Beehive design in my own project?

Yes, under the terms of its MIT license, which BeeHive-org chose for the repository.

Can I test firmware for the Beehive 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.
