ESP32-S2-Saola-1 uses a WS2812 as an indicator light, which can display various colors. In earlier versions of CircuitPython, ESP32-S2 does not support WS2812, but in the latest circuitpython 6.0 beta...
I recently repaired a circuit board. When mapping the schematic diagram, I found a current amplifier circuit. It used an op amp LF356, without any peripheral devices. Pin 2 was directly connected to t...
How to connect the freewheeling diode? If it is connected as shown in the picture, it should not be removed. If it is not connected, the reverse voltage will cause the VS voltage to increase....
Since the UWB (Ultra Wide Band) system uses a broadband of more than 500MHz to transmit data at high speed, the UWB antenna must have good frequency characteristics. In recent years, OFDM (Orthogonal ...
