About the ESPFLASHER PCB

ESPFLASHER is an open source PCB design by nuclearcat, published on GitHub under the LGPL-2.1 license. It is a 2-layer board measuring 40 × 21 mm, with 17 components from 12 distinct parts.

Other key parts include the TLV1117LV33DCYR, SRV05-4 and CH340C. By type, the board carries 5 resistors, 4 capacitors, 3 ICs, 2 transistors, 2 connectors and 1 diode.

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

From the project

Inexpensive ESP32/ESP8266 programmer

This device implements a USB programmer for ESP32/ESP8266 devices with traditional programming pin management (EN/BOOT0) using [RTS DTR bridge][1].

It also differs from traditional USB-UART converters by a powerful LDO, which allows you to easily power the ESP32 / ESP8266 and related peripherals. Earlier revisions were manufactured by JLCPCB and tested for programming various devices.
