Curve Tracer with Raspberry Pico

Here a preview of the curve tracer with RP2040. It works with an IL9341 tft-SPI-display with touch. Next to the Rapid_Development board for the Pico I use the constant-currentsource with HC595 and the new Power board for driving Uce. It works with 12v, powered from a 18650 lion-cell. The Power board includes an 12 bit ADC MCP3204, a Dual-DAC MCP4822 and an "power"-amplifier (TCA0372).. You can measure with it "normal" bipolar transistors ((n/p), diodes (and zener < 12V) .J-Fets and Mosfets.
Some fields are also changeable with 2 rotary encoders.
In the next days I will present the new Power-Board for changing Uce with Dual-Dac.
