The Raspberry Pi microcontroller 24-channel 100Msps logic analyzer has been upgraded to support 120 channels.
Daisy chaining of five devices is supported, allowing capture of 120 channels. Includes performance improvements and visibility improvements to the rendering engine, more samples in the screen, automatic selection of capture modes, editing capabilities, and more. The playability is getting higher and higher.
Pocket calculator style general purpose programmable device (computer) ideal for learning programming and improving building/soldering skills.
Open source material for the Arduino UNO Mini Limited Edition.
The collection of papers from previous electronic design competitions includes design ideas, circuit diagrams and corresponding program flow charts for function signal generators, oscilloscopes, automatically controlled balancing cars, radios, etc.
This is a mature development board combined with a magnetic rotary encoder, which uses a Raspberry Pi RP2040 microcontroller with a base resolution of 36, expandable to 36,000 steps per revolution.
The Raspberry Pi microcontroller itself does not have an Ethernet MAC, but it can be easily implemented through the programmable IO of the Raspberry Pi. The programmable PIO of the Raspberry Pi microcontroller that costs 5 yuan a piece is indeed a miracle, with IO below 250MHz. Control everything.
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. This design is a JTAG programmer based on FT232H.
This is a simple USB sniffer based on the Raspberry Pi RP2040. It supports low speed and full speed modes. The firmware presents itself as a virtual COM port (VCP), so no additional software is required and it is compatible with all operating systems.

The PicoCray project connects multiple Raspberry Pi Pico microcontroller modules into a parallel architecture, utilizing the I2C bus to communicate between nodes
The lazy self-care fish tank control system is mainly aimed at fish farming enthusiasts. As long as you use your mobile phone through BLE, you can manually control the start, stop, and feeding of the fish tank's electrical appliances. At the same time, the real-time time, supplementary lighting time, automatic feeding time, water temperature monitoring and alarm, etc. can be set through the APP at once. Enthusiasts are only responsible for watching and appreciating the fish, and the other things are left to the control system!
These demos all use Adafruit's PicoDVI branch, which makes the video framebuffer look like a regular Adafruit_GFX object, which makes drawing very easy.
The system developed in this article is based on the existing triggered voice time reporting system, adding a speech recognition circuit, so that the developed system can have the function of dialogue response time reporting, and realize the truly automated and intelligent voice time reporting.
