icebreaker++: icebreaker FPGA board, upgraded ECP5

One of the open source PCB projects designed with KiCad by Gregory Davill

Overview

Gregory Davill is a technical expert from Australia who is very famous and active in the field of open source hardware. In December 2020, he insisted on designing a circuit board every day, using KiCad to complete the circuit design and PCB layout and routing. This is the adventure-calendar-of-circuits-2020 project.

icebreaker++ is a very nice and convenient little board. But it has a small flaw, the ice40 FPGA it uses is very simple, and it's generally fun to see people doing exciting projects with 5k LUTs. Sometimes it's convenient to have some extra space available when experimenting.

- The board design is based on the original design, simply replacing the fpga with ECP5.

- The second port of FTDI connects directly to additional I/O pins.

- Each PMOD is connected to support 4 differential pairs.

USB Type-C Connector Introduction
Compared to its USB predecessors, USB Type-C does not require worrying about plugging it in upside down, and its power delivery and data transfer are also good, so it is becoming increasingly popular
Fly-Buck Converter PCB Layout Tips
Synchronous buck converters have been proven as isolated bias supplies in the communications and industrial markets. The isolated buck converter, or Fly-Buck converter as it is commonly called, uses a
[Graphics Library] Teach you how to make pictures and display them using the graphics library~
I just got a TI Cotex-M4 development board. I played with it for a while and it was very cool. I have heard about TI's graphics library for a long time. I quickly wrote a program in IAR to try it out.
Problem with connecting the resistor between BE when the transistor is used as a switch.
When a transistor is used as a switch, which of the three ways of connecting the resistor between BE and transistor is correct? Why? Please enlighten me, my analog electronics is really poor.

Problems with measuring high frequencies using an oscilloscope voltage probe
I used the voltage probe of an oscilloscope to measure the voltage signal on a high-frequency resistor, and found that as soon as the voltage probe was connected, the signal reflection was very strong
