ImpBox32
About the ImpBox32 PCB
ImpBox32 is an open source ESP32 PCB design by AmigaPorts, published on GitHub. It is a 2-layer board measuring 44 × 40 mm, with 28 components from 16 distinct parts.
Its main chip is the ESP32-WROOM-32D, from the ESP32 family. Other key parts include the AMS1117-3.3 and CBTD3384. By type, the board carries 6 capacitors, 5 resistors, 4 ICs, 4 connectors, 3 diodes and 2 jumpers.
It belongs with the iot & wireless, retro computing and displays & leds designs in this gallery.

Wireless connectivity for your Amiga
This device provides wireless connectivity to your Amiga. The primary purpose is for use with IMP, but with proper firmware it can act as general-purpose network interface.
Flash the device with firmware from firmwareimpbox` directory - you can use RX/TX pin header for this using typical ESP32 tooling. Assuming that your COM port is /dev/ttyUSB0:
The IMP firmware automatically updates itself, so you need to flash it manually only once.

ImpBox32: common questions
What microcontroller does the ImpBox32 use?
The ImpBox32 is built around the ESP32-WROOM-32D, from the ESP32 family.
How big is the ImpBox32 PCB?
The ImpBox32 measures 44 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ImpBox32?
28 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the ImpBox32 design files?
From the AmigaPorts/ImpBox32 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ImpBox32 design in my own project?
The repository has no license, so all rights stay with AmigaPorts. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ImpBox32 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.
