Thingler ESP32 Programmer

Thingler ESP32 Programmer is a USB Type-C to UART ESP32 programmer. The programmer is based on the CP2102N chip with two tactile buttons, BOOT and EN. The programmer can also be used to power the ESP32 (3.3V) chip and read log data sent from the ESP32 chip.

Thingler ESP32 Programmer has been designed for the Thingler ESP32-PICO-D4 Module but can be used to program any ESP32 chip.

Thingler ESP32 Programmer schematics and PCB has been designed with KiCad.

Getting started

Requirements

• Follow Espressif Systems Getting started instructions

• Silicon Labs drivers in case the programmer is not recognized by the computer

• KiCad for the schematics

Build

The PCB wihout components can be ordered from Aisler or the PCB can be ordered from any fabrication houses by providing the gerber files.

The following components has been used for the programmer:
