About the Bisque PCB
Bisque is an open source ESP32 PCB design by BenSeverson, published on GitHub under the MIT license. It is a 4-layer board measuring 100 × 100 mm, with 159 components from 63 distinct parts.
Its main chip is the C3013945, from the ESP32 family. Other key parts include the C48937499, C2653162, C7420376, C7512 and C515890. By type, the board carries 64 resistors, 43 capacitors, 14 connectors, 12 ICs, 9 diodes and 7 transistors.
From the project
ESP32-S3 ceramic kiln controller with web UI, PID control, and safety systems
The controller board. This is rev B, a respin of the original prototype rather than a variant — it replaced the thermocouple front-end with an incompatible part, added a second SSR zone and a digital current-sense chip, moved most GPIOs, and swapped the module variant. 4-layer, 100 × 100 mm, built for JLCPCB assembly: 0805 passives, QFN/TSSOP/SOIC/SOT ICs, SMD tact switches and the ESP32-S3-WROOM-1U module's castellated pads all go down the SMT line, plus thirteen through-hole parts (terminals, wafers, buzzer) fitted by hand — see "Fabrication & assembly" below for why that split is much…

Bisque: common questions
What microcontroller does the Bisque use?
The Bisque is built around the C3013945, from the ESP32 family.
How big is the Bisque PCB?
The Bisque measures 100 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Bisque?
159 components, from 63 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 Bisque design files?
From the BenSeverson/bisque 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 Bisque design in my own project?
Yes, under the terms of its MIT license, which BenSeverson chose for the repository.
Can I test firmware for the Bisque 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.
