This project is a WiFi Camera with Motion Detection, utilizing ESP32-CAM module and HC-SR501 PIR sensor. The camera is activated by the sensor's output. The system also includes power regulation and communication headers for setup and control. #WiFi #MCU #PIR #ReferenceDesign #project #ESP32 #camera #referenceDesign #edgeComputing #espressif #template #reference-design

Guitar pedal starter template based on project by Mark Wu. Includes schematic and PCB layout for basic DIY pedal hardware. This includes two 1/4" jacks (one for input and one for output), a 9V power supply (including LED), a 3PDT true bypass wiring setup, and an example potentiometer that can be copy/pasted throughout the circuit. The headers are meant to be unpopulated so that wires can be soldered to the pads. PCB design rules imported from the JLCPCB 2-layer stackup template. #template
