QUARK is a new wireless multitool that aims to simplify the development of electronics on open source hardware like Arduino, ESP32, and STM32. Its sleek design, looking similar to a price scanner, makes it easy to hold in one hand with touch-sensitive controls on the body of the device.
It has a bright, full-color screen that displays information about the hardware. The screen connects to a built-in probe, with a second probe that connects to a USB Type-C connector. If the 240x135 screen isn’t big enough for you, it can be connected to QUARK's smartphone app for a larger screen view and to configure the probes for other uses.
Thanks to its easy touch interface, you can change QUARK’s operation modes with a single swipe — voltage measurement mode that shows logic levels and amperage measurement mode, which builds a graph of the change in values. It can also measure the values of resistors, inductors, and capacitors, which includes the measured value and color and code markings. The scale can be adjusted with the oscilloscope (manually and automatically), and UART mode adjusts the baud rate and shows the data stream.
QUARK can be used for a variety of applications, such as Arduino, STM32, and ESP32 development, power supply debugging, electronics repair and diagnostics, and sensor diagnostics. Radio enthusiasts, auto electricians, hobby and professional makers, and drone operators may also find QUARK to be a handy tool.
