About the Teacup carrier merge test PCB
Teacup carrier merge test is an open source ESP32 PCB design by thingino, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 257 × 117.5 mm, with 131 components from 95 distinct parts.
Its main chip is the ESP32-S3-WROOM-1-N16R2, from the ESP32 family. Other key parts include the AZ1117-3.3, AZ1117-1.8, MCP4661-104E_ST, W25Q32JVSS and AZ1117CH-3.3TRG1. By type, the board carries 42 resistors, 28 capacitors, 26 connectors, 15 ICs, 11 jumpers and 3 inductors.
It belongs with the dev boards & breakouts and iot & wireless designs in this gallery.
From the project
Universal Ingenic SoC development platform: one carrier + per-SoC interposer modules (T10 through A1, any package) on a DDR4 card edge, with an ESP32-S3 BMC for autonomous LLM-driven development.
A universal development platform for any Ingenic SoC — T10, T20, T21, T23, T30, T31, T32, T33, T40, T41, and the A1 NVR processor — regardless of package (QFN88 / QFN96 / BGA232 / BGA356 / BGA381).
Two boards: - a carrier — the universal baseboard: adjustable SoC power, all peripherals, full pin breakout, and an on-board ESP32-S3 management controller so an agent (an LLM, CI, or a human) can drive the target wired or wireless — flash, reset, boot-select, console, and voltage-margin it hands-off; - a small per-SoC interposer — the SoC + its package fanout + clock + decoupling + straps (+…

Teacup carrier merge test: common questions
What microcontroller does the Teacup carrier merge test use?
The Teacup carrier merge test is built around the ESP32-S3-WROOM-1-N16R2, from the ESP32 family.
How big is the Teacup carrier merge test PCB?
The Teacup carrier merge test measures 257 × 117.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Teacup carrier merge test?
131 components, from 95 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 Teacup carrier merge test design files?
From the thingino/teacup-neo repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Teacup carrier merge test design in my own project?
Yes, under the terms of its GPL-3.0 license, which thingino chose for the repository.
Can I test firmware for the Teacup carrier merge test 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.
