About the Trace memory pebble hackathon PCB

Trace memory pebble hackathon is an open source ESP32 PCB design by hupop444, published on GitHub. It is a board, with 20 components from 13 distinct parts.

Its main chip is the ESP32-S3-DevKitC-1, from the ESP32 family. By type, the board carries 8 resistors, 6 capacitors, 3 connectors, 2 diodes and 1 IC.

It belongs with the iot & wireless designs in this gallery.

From the project

TRACE Memory Pebble — three-device ESP32 physical-computing system with pressure, ambient light, haptics, synchronized web software, CAD and electronics.

TRACE 是面向千人黑客松现场的完整软硬件交互原型。ESP32-S3 / ESP32-C3 Pebble 采集压力与环境光,统一 WebSocket 网关将真实硬件事件精确路由到三位用户的软件空间;用户补写一句话后,Memory Gardener 将瞬间生长为可回访的记忆。回放始终携带原始 eventid`,因此触觉反馈会返回最初捕捉它的那块 Pebble。

- 两种 ESP32 规格共用一套 Wi-Fi 固件与交互协议。 - 压力捏取触发、短振捕捉确认、双段触觉回放。 - 环境光与压力时长作为 Moment 的现场上下文保存。 - 三屏 / 三用户隔离:deviceslot、profileId`、事件去重与精确回放。 - 真实设备不足时按槽位补入独立模拟器,演示流程不中断。 - 手机宽度产品界面:认领、生长、花园、年轮、旧日重逢、后来补充。 - 可用的提醒设置、隐私说明与 JSON 记忆导出。 - 参数化 OpenSCAD 外壳、KiCad 传感器板、BOM、打印与视觉资产。

Trace memory pebble hackathon: common questions

What microcontroller does the Trace memory pebble hackathon use?

The Trace memory pebble hackathon is built around the ESP32-S3-DevKitC-1, from the ESP32 family.

How many components are on the Trace memory pebble hackathon?

20 components, from 13 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 Trace memory pebble hackathon design files?

From the hupop444/trace-memory-pebble-hackathon repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Trace memory pebble hackathon design in my own project?

The repository has no license, so all rights stay with hupop444. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Trace memory pebble hackathon 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.
