The ESP32-C3 is a WiFi SoC that contains a RISC-V core in place of the Tensilica core in the ESP32 we are all familiar with. It uses the ESP8266 pin-out. As with other ESP32 family members, this one delivers b/g/n WiFi and Bluetooth LE 5, where it differs is the RISC-V 32 Single-core...

Conductive materials change their properties under strain or stretching. The electrical conductivity decreases and resistance increases with stretching. The US Air Force Research Laboratory (AFRL) is working with liquid metal systems that can autonomously change the structure to become...

Monolithic Power Systems (MPS) MP8833x Thermoelectric Cooler Controllers feature built-in internal power MOSFETs and achieves 1.5A continuous output current. These controllers include TEC current monitor, external SYNC function, and EN/SD for power sequencing. The MP8833x cooler...

This is a 3-channel, PWM based current-adjustable LED driver designed for RGB LED control. The circuit has been designed to control high current RGB LEDs or RGB LEDs strip. Colors of the three RGB LEDs can be set using 3 potentiometers, different colors are possible by adjusting these...

This project provides an economical and precise solution for DC current sensing and display on an OLED display. This board uses the ACS715T-20A hall effect-based linear current sensor chip, 0.96 Inch I2C OLED Display and Atmega328 microcontroller chip. It is an Arduino compatible...

This Arduino shield transforms your Arduino UNO into an ISP-Programmer for the ATtiny85 microcontroller. The board simplifies the Boot-loader burning on the ATtiny85 chip. It consists of an 8-pin DIP socket to insert the new ATtiny85 chip, C1 decoupling capacitor, and C2 capacitor is...

PCB design guide for an inverted-F 2.4 GHz antenna from Silicon Labs. One of the main reasons to use a PCB antenna is to reduce cost. Since the antennas are printed directly on the board, they are generally considered to be free. On boards with room to spare, this will be true. On...
