A breakout board for a mini linear stepper motor with a 4 pad connector on 0.8mm centers. The board has holes for mounting the frame using solder.

All sizing is guessed, this is my 4th version, V3.1, after size testing the previous 3. The motors are available on Amazon in qty’s of 50 there is no documentation on these, but I’ve been toying with the measurements and custom PCB’s for months… I will update this description with photos of the actual boards populated with the motors.

The plastic nut on the shaft of these motors take very small stiff wire lodged in the opening and it will have about 4mm of motion. The wire should be about 0.2mm to 0.4mm, very thin! Soldering by hand needs to be done very quick or the flex material will melt, even with a 110V - 15W iron. Very little room for error when soldering.

This board is hopefully the final test, but it may need further revision.

Design files at: https://github.com/mike-rankin/ESP32_Desktop_Clock HackaDay link: https://hackaday.com/2021/10/27/esp32-clock-takes-time-to-give-weather-info-too/ This ESP32 internet of things desktop clock is a project created for my home. School has started and fall is coming so every morning my kids ask me what they should wear. This clock is normally very, very dim and shows the time, co2 value, room temperature and humidity in a dark orange color. When you move your hand a foot or so in front, the time fades away to a screen showing the days low temperature, high and what the weather conditions will be. Time is updated every few minutes over wifi from an NTP server, local weather data is updated from Openweather with various sensors on the front.

Hardware on this board: -ESP32 Pico D4 processor -temperature/humidity sensor (HDC1080DMBT) -laser range sensor (VL53L0CXV0DH) -CO2/TVOC (SGP-30-2.5K) -ambient light sensor (BH1750FVI) -135x240 TFT LCD (ER-TFT1.14-1) -3.3V LDO (NCP1117LPST33T3G) -1.8V LDO (RT9193-18GB) -Neopixel LED -USB interface (CP2104N) -USB-C Connector -QwiiC i2c Connector -Buzzer
