# is0Topre

## Introduction

Topre version of the iconic is0 board.

This project is a continuation of my development of open source EC boards.

Below is the KLE of the supported layout:

![is0Topre KLE](/Assets/images/is0Topre_KLE.jpg)

## Technical information

- Layout size: ISO enter

- Compatible switches: EC switches (Topre and NIZ)

- Microcontroller: Atmega32u4

- Connector: USB Type C

- Firmware compatibility: QMK (with VIA/VIAL support)

- Protection hardware:

  - Fused

  - ESD protection

**Addition: an empty spot for a 3.5x3.5mm SK series LED has been added to the back of the PCB, in case you want to manually add a bit of lighting.

## WIP

Atmel MCU based firmware is validated, you can find the precompiled `.hex` (Vial compatible) and `.json` file for VIA in the firmware folder.

STM32 based MCU version is in development.

## Compatibility with is0 case

Given the difference in height and mounting system some modifications are needed.

At the time of ordering the PCBs be sure to use the following specs:

- 1.2mm thickness for the main PCB

- 0.6mm for the plates

In order to have the correct fit place in the marked spots adhesive tape, specifically:

- 2pcs, 0.4mm thick on the main PCB

- 4pcs, 0.1mm thick on the plates

These will ensure that all the tollerances are met and a secure fit is achieved.
