About the CONNECT programmer PCB

CONNECT programmer is an open source PCB design by SolderedElectronics, published on GitHub under the TAPR-OHL-1.0 license. It is a 2-layer board measuring 22 × 38 mm, with 24 components from 17 distinct parts.

Other key parts include the CH340C and SE5218. By type, the board carries 7 resistors, 4 capacitors, 3 diodes, 2 ICs, 2 transistors and 2 relays.

It belongs with the usb & debug tools designs in this gallery.

From the project

Hardware design, BOM, gerbers and 3D files for CONNECT-programmer designed by Soldered Electronics.

CONNECT programmer is designed to allow extremely simple programming of boards based on ESP8266 and ESP32 microcontrollers. It contains all the necessary electronics and logic so that programming can be done by plugging USB cable into CONNECT programmer and connecting CONNECT programmer to the programming header. Electronics that take care of timing and signal sequence are also on board, so it puts the ESP uC into bootloader mode.
