About the Neatboard esp8266 PCB

Neatboard esp8266 is an open source ESP8266 PCB design by galjonsfigur, published on GitHub under the MIT license. It is a 2-layer board measuring 28 × 34.2 mm, with 49 components from 35 distinct parts.

Its main chip is the ESP8266EX, from the ESP8266 family. Other key parts include the CP2102N-A01-GQFN28, AT25SF081-SSHD-X and LM3671. By type, the board carries 15 resistors, 12 capacitors, 4 ICs, 4 diodes, 3 connectors and 3 jumpers.

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

From the project

My version of D1 Mini with ESP8266 and many neat features

Small clone of WeMos D1 Mini couple additional functionalities: - Pin-out and footprint compatible with WeMos D1 Mini (exception: board outline) - Additional jumpers for Deep Sleep and disabling LEDs - CP2102 USB-UART bridge (no more problems with CH340) - UART activity LED - DC/DC instead of LDO for better efficiency - Bigger PCB antenna, based on DN007 document from Texas Instruments - Integrated Fuse and ESD protection
