The S32K3X4EVB-Q257 is a full-featured evaluation and development board for general automotive applications.
ST has previously launched a board with a static current measurement range of 1nA - 100mA and a dynamic current measurement range of 100nA - 50mA, but it is not open source. This time it’s open source.
A simple oscilloscope made of STC8A8K MCU. The microcontroller uses STC8A8K64S4A12 working at 27MHz. The display uses a 0.96 OLED with a resolution of 128x64. This oscilloscope project is easy to start and covers the necessary measurement functions. Supports normal mode, single mode, and automatic mode. It has trigger mode selection, such as level trigger, and comes with saved settings. Mini-DSO input is single-channel mode, and the second/division size can support a variety of: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100us, and the voltage acquisition range is 0 to 30V. The sampling rate can reach 250kHz@100us/div.
This ESP32-based FPV car can stream video over Wi-Fi and only needs a small LiPo battery for power. It can be controlled remotely and accurately through any web browser.
This reference design board supports the NXP® MM912_P812 engine control IC, which combines an MCU (S12P) and an analog control chip (MC33812), and is suitable for motorcycles and other single/double-cylinder small engine control applications.
The analog control IC consists of three integrated low-side drivers, a pre-driver, a +5.0 V voltage pre-regulator, an MCU watchdog circuit, an ISO 9141 K-Line interface and a parallel interface for MCU communication.
