About the DevKitTell PCB

DevKitTell is an open source ESP32 PCB design by NikolasKelava, published on GitHub under the MIT license. It is a 4-layer board measuring 25.5 × 62.8 mm, with 26 components from 19 distinct parts.

Its main chip is the ESP32-S3-MINI-1-N8, from the ESP32 family. Other key parts include the USBLC6-2SC6, TLV75801PDRV and BQ24040DSQR. By type, the board carries 8 resistors, 7 capacitors, 4 ICs, 2 connectors and 2 diodes.

It belongs with the iot & wireless, keyboards and displays & leds designs in this gallery.

From the project

A custom, wireless Bluetooth LE macro keypad (12 keys + magnetic rotary encoder + OLED) built on an nRF52840 module and running ZMK

A custom, wireless Bluetooth LE macro keypad with 12 mechanical keys, a magnetic rotary encoder, and a 128×64 OLED built on a Nordic nRF52840 module and running ZMK. Keys and profiles are configurable live over ZMK Studio; the encoder is a per-profile knob (volume / vertical scroll / horizontal scroll / browser tabs). Battery-powered (2000 mAh LiPo) with USB-C charging.

DevKitTell: common questions

What microcontroller does the DevKitTell use?

The DevKitTell is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the DevKitTell PCB?

The DevKitTell measures 25.5 × 62.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the DevKitTell?

26 components, from 19 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 DevKitTell design files?

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

Can I use the DevKitTell design in my own project?

Yes, under the terms of its MIT license, which NikolasKelava chose for the repository.

Can I test firmware for the DevKitTell 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.
