About the Teensy4 esp32 sd usb host breakout

Teensy4 esp32 sd usb host breakout is an open source ESP32 PCB design by blackketter, published on GitHub. It is a 2-layer board measuring 22.9 × 55.9 mm, with 33 components from 25 distinct parts.

Its main chip is the ESP32-WROOM-32D, from the ESP32 family. Other key parts include the TPD3S014 and TLV75733PDBVR. By type, the board carries 9 resistors, 8 capacitors, 7 connectors, 3 ICs, 2 diodes and 1 battery holder.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Breakout board for Teensy 4.0 with ESP32, SD slot, USB Host (and more)

A jumbo breakout board with ESP32, USB-A host and microSD connectors to mate with the Teensy 4 Header Breakout Board.

Additionally, the board includes a space for RTC Battery Holder and provides another Teensy reset/programming button (since it covers up the one on the Teensy).

It's designed to mount above or below the Teensy 4 and Header Breakout board on a relatively tall header.
