BitDogLab

BitDogLab, an initiative of the School Project 4.0 at Unicamp, is an educational tool devoted to electronics and computing. Based on Raspberry Pi Pico H or W, it allows users to explore, assemble, and program using components mounted on its board and also external ones connected in an organized and secure manner. Meticulously selected, the components foster hands-on learning, encouraging users to enhance programming and electronics skills synergistically and progressively. This enriching platform offers a vibrant experience, immersing users in a colourful, auditory, and synesthetic learning environment. Additionally, BitDogLab is optimized for programming assisted by large language models (LLM), like GPT-4, facilitating a more intuitive learning guided by a tireless tutor. Aimed at pre-university education, BitDogLab aims to catalyze the incorporation of educational technology, providing a robust and flexible tool uniquely integrated into students' learning journey.

A hallmark of BitDogLab is that its project is entirely open, allowing it to be freely copied, manufactured, assembled, and improved by users. More information at: https://github.com/Fruett/BitDogLab

This repository holds open-source design files for BitDogLab, an educational STEAM tool. It includes various components like LEDs, buzzers, buttons, and more, promoting collaborative modification and enhancement of STEAM education.

Firmware v1.0 da BitDogLab with Micropython 1.22.1

BitDogLab Firmware was compiled on 02/04/2024 and already includes the following 3rd libs:

• ahtx0 (Sensor de temperatura/umidade AHT10 i2c)
• bh1750 (Sensor de luminosidade i2c)
• ssd1306 (Oled i2c)

To enter ther bootloader mode, hold bootsel button on the raspberry pi. After, copy the new firmware. If you want to guarantee a new instalation, copy clean.uf2 before.
