Introduction: The homemade SP200S programmer can write simulation firmware for SST89E516 and SST89E58 chips. Fix the SST chip that cannot be emulated or downloaded due to firmware issues.
Introduction: VDF open source screen driver uses the SPI interface on the board, with a photoresistor part, onboard w25Q64 Flash and Bluetooth to serial port module.
Introduction: HiSilicon Hi3861V100 core board supports OpenHarmony and has been verified.
Introduction: DJI Innovations, Mavic Mini drone data cable.
Introduction: Convert the SMD microcontroller to a direct plug, adapting to the onboard 12Mhz crystal oscillator of most development boards on the market.
Introduction: USB voltage and ammeter based on ESP32-PICO-D4+INA226, using TYPE C male and female connectors; touch button to switch display direction; focus: ultra-thin, simple
Introduction: Far-infrared heating, placed above the PCB, with a fan below to dissipate heat, can achieve two-sided (twice) patch welding; three thermocouples, real-time monitoring of the temperature of the heating plate, the temperature of the upper surface and lower surface of the PCB; step-by-step The motor automatically lifts and lowers, cooling down faster after welding.
