About the ESP Attiny 1614 PCB

ESP Attiny 1614 is an open source ESP8266 PCB design by tomtor, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 33.1 × 23.9 mm, with 18 components from 14 distinct parts.

Its main chip is the ESP-01v090, from the ESP8266 family. Other key parts include the ATtiny1614-SS and MCP1700-3302E_TO92. By type, the board carries 5 resistors, 4 capacitors, 3 ICs, 3 connectors, 2 diodes and 1 crystal.

It belongs with the power & battery designs in this gallery.

From the project

KiCad ATtiny84/x14/x02 (SMD) and ESP-01 (ESP 8266) PCB boards

The main function of the ATtiny is acting as a battery friendly low power co-processor for the ESP. A bit like the ULP low power co-processor of the ESP32, except with a lot more IO functions and program memory.

ATtiny and ESP combined use 22uA in sleep mode or even less when the ESP is switched off by the ATtiny with CS.

Usable on breadboard (ATtiny84: 9 rows high, leaves 2 rows empty and ATtiny16x4: 8 rows high) OR stand alone.

ESP Attiny 1614: common questions

What microcontroller does the ESP Attiny 1614 use?

The ESP Attiny 1614 is built around the ESP-01v090, from the ESP8266 family.

How big is the ESP Attiny 1614 PCB?

The ESP Attiny 1614 measures 33.1 × 23.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP Attiny 1614?

18 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP Attiny 1614 design files?

From the tomtor/ESPTiny repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP Attiny 1614 design in my own project?

Yes, under the terms of its GPL-3.0 license, which tomtor chose for the repository.

Can I test firmware for the ESP Attiny 1614 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
