About the Caravel breakout QFN

Caravel breakout QFN is an open source PCB design by nic0villegasc, published on GitHub. It is a 2-layer board measuring 150.5 × 110.5 mm, with 60 components from 33 distinct parts.

Other key parts include the Caravel, AZ1117-5.0, AZ1117-1.8, LM2576T-5 and LM2575-5.0BT. By type, the board carries 25 connectors, 19 capacitors, 7 ICs, 5 inductors, 2 diodes and 2 resistors.

It belongs with the displays & leds and dev boards & breakouts designs in this gallery.

From the project

In this repository I will save all the code that I used to run the LushayLabs examples.

This repository serves as a collection of Verilog/SystemVerilog examples and projects for the Sipeed Tang Nano 20K FPGA development board.

These projects are adaptations of the Lushay Labs Tang Nano 9K tutorials, modified to accommodate the specific pinouts, constraints, and logic levels of the 20K variant. The repository covers practical FPGA implementations ranging from basic logic to complex peripheral drivers (I2C, SPI, UART).
