ESP32S2 + Sharp memory LCD + prototyping area
The icebreaker project is a very nice and handy 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.
This computing watch is designed using the SAML22 ARM microcontroller. This particular microcontroller has a segmented LCD controller capable of driving the LCD used inside the watch.
This project includes all the software and hardware design required to develop the T12 soldering station. The PID parameters are mature and the function completion is very high.
Mega-Cube is a light cube that drives 4096 LEDs based on PL9823. The main control is Teensy4.0 based on NXP i.MXRT1060 FlexIO function and many 595 shift registers. It can control up to 32 channels, each channel 1000 LED.
In the open source electromyography project shared here, the author used this product to create a computer game control effect.
The Sensor Watch is unlike most smartwatches.
Little Bee is an affordable, high-performance current probe and magnetic field probe that allows you to debug and analyze electronic devices more efficiently.
The biggest highlight of this kit is Sony's own 6-core microcontroller CXD5602, which comes with 1.5MB of general-purpose SRAM, 64KB of backup SRAM, and a main frequency of 156MHz. There is also an M0+ core assist processor for IO control management, which comes with 256KB of general-purpose SRAM. The built-in GNSS receiver supports GPS and GLONASS. Others include 2D graphics acceleration (supporting rotation, scaling, mixing, etc.); dedicated sensor acquisition peripherals (with its own 40KB FIFO and supporting preprocessing) supporting SPI, I2C and other interface methods; DCMI camera interface and I2S audio peripherals All pretty good too.
All information is fully open, and there is also a mobile APP, and the algorithm is also made public.
The goal of PSLab is to create an open source hardware device (with all resources fully open) that can be used by electronics enthusiasts to do experiments. And offers a range of sensors for engineering experiments, including oscilloscopes, waveform generators, frequency counters, programmable voltage, current sources and data loggers.
STMBL is an open source servo driver designed for CNC machine tools and robot modifications. It supports industrial AC and DC servos up to 320V and 2kW.
The MAXREFDES1206 is a Power over Ethernet (PoE) powered device and active clamp forward converter that delivers up to 1A at 24V from a 39V to 57V supply voltage.
This reference design boosts a single-cell battery voltage to a 10W output using the MAX669 controller in the bootstrapped mode.
MAXREFDES1255 is a 4-switch buck-boost converter that gives a positive step-up/stepdown output voltage.
The MAXREFDES1219 is an integrated smart solution for the 1-cell Li+ battery pack that provides a linear charger
The DS28E18 is an easy-to-use bridge integrated circuit (IC) that operates as a 1-Wire® slave device to a host controller.
The MAXREFDES1274 is a buck converter using the MAX17501F high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs and internal compensation.
The MAXREFDES1275 has three main blocks: the microcontroller, ADC/DAC IC MAX11311, and three LED drivers.
