Level-shifterThe USB to RS232 outputs only 3,3V on TX signal. But the board provides both 5V and 3.3V output for driving external Electronics. The hardware I will use this level-shifter om has also the RX signal inverted. Thats the reasson for only Three Inverter gates. I would likely used four of them on a normal USB to RS232 with level-shift, or maybe an 74HC04 SO. But I allready had these gates and the cheep Silabs USB to RS232 laying in my drawer. Next time I'll redesign and fit all in one PCB. The requirement is a small design. It will be used between a Raspberry Pi 3 and an home appliances in our labratory at my work. BTW... Thank you PCBGOGO for the high quality and Quick delivery of the PCB-boards. You also gave me a few extra boards :) and immersion gold for free.4238 0 Jan 20.2018, 19:25:01 -
HerculesHercules is a very small size module that cand drive up to four step motor with microstepping tecnique. But at the same time it can be used as a controller or a complete instruments. Drive bipolar motor up to 3A rms and with a supply voltage from 9 to 24VDC (up to 40VDC under request). To change its functionality simply upload a prebuilt binary with a dedicated utility. Many free ready to use functions are available. Is available with different models according to number of controlled motors, connectors or for heavy duty use.5415 0 Jan 17.2018, 14:13:25 -
Deagostini Millennium Falcon ControllerCustom PCB for an Arduino Mega shield for controlling the bespoke lighting and sound of my Deagostini Millennium Falcon model. Lights, sounds and ramp control are all independently controllable from phone application.6778 0 Jan 12.2018, 01:00:37
