ESP8266 based slave board for controlling power supply based on a central control unit.

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.4752 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.5918 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.7460 0 Jan 12.2018, 01:00:37

Hey, I’ve seen projects like that with ESP8266 boards, I tried messing with similar setups once and it got frustrating when things didn’t work as expected, especially after long evenings of testing, so I started looking for simple ways to unwind after that, and one night I randomly found https://spinkings.uk it mentioned bonuses for players from United Kingdom so I gave it a try started with Gates of Olympus lost a few rounds but then took a bigger chance and hit a solid win, now I sometimes use it to relax instead of stressing over small technical issues.

Girando per le strade di Genova ho visto un annuncio che mi ha spinto a fare un ultimo tentativo. Ero in un momento difficile, perdevo ogni singola scommessa e stavo quasi per rassegnarmi a chiudere definitivamente i conti. Poi però ho aperto https://casinias.it e la situazione è cambiata radicalmente. Ho beccato una mano fortunata che mi ha fatto recuperare ogni centesimo perso e mi ha lasciato pure un bel gruzzolo. Sono davvero molto soddisfatto.

This nodeMCU layout is brilliant! I ordered a similar custom PCB from here for our optics lab in Texas. We are using the ESP8266 to monitor temperature and current drivers for a high-end semiconductor optical amplifier in our test rig. The manufacturing quality of this US prototype is great, making it super easy to integrate IoT controls directly into our complex telecom hardware
