The voltage sensor module is a 0-25 DC voltage sensing device that is based on a resistive voltage divider circuit. Earlier, we made 0-50V DC Voltmeter to measure the output voltages & also learned about the DC−to−DC converters. In this tutorial, we will learn interfacing of 0-25V DC Voltage Sensor with Arduino to measure DC Voltages.

Voltage Sensor Module Design & Construction.

Waiting to see if more bus changes are needed.Įdit4: (may be a record ) Fix one pad in pcb that was off by 0.25mmĮdit5 Mar 9 2021: Corrected pins D2 and D3 in schematic which were reversed in the original part, so schematic was wrong.) This may be good enough, we will see.Įdit3: removed RST from bus as they are all seperate, centered the usb connector and CPU chip in breadboard.

The down side to making this change (and why I didn’t do it here) is that it will break all existing sketches. As it stands the pin numbers are not contiguous and that usually causes problems with the hover on the pin and it displays the description code although in a quick test I can’t see it happening. If I get ambitious (or bored or frustrated with development ) I may fix this properly and renumber the pins. Fair warning, something I managed to do in the test sketch has managed to offset the silkscreen in the gerbers (for only the test sketch, just a part has the silkscreen correct) which I can’t see any reason for so I think the part works. OK, here is a properly updated version of this part.

There are versions without headers, but this the version with female headers attached to the underside.ĮDIT : My part is probably wrong - I don’t have one to check -, so use the one in the post below.ĮDIT EDIT - Of course check if a newer one appears, but this is the LINK to current correct part 17th Feb 2019 below - Mega2560 R3 Pro Mini With Atmega16U2 chip as the USB to Serial converter It’s cute and small size.Ĭompletely compatible with original Arduino Mega2560 For the original Mega2560 it has a big board size, some time it maybe not easy to embed it into your system, the Meduino Mega2560 Pro Mini board will be more easy for embedding it into your system. It’s completely compatible with the original Arduino Mega2560. This Meduino Mega2560 Pro Mini board is a small version of the Mega2560 board. Other photos show it plugs into prefboard, so I assume it’s 21 x 15 pins on a 0.100' pitch. This was made entirely from online photos and guess work, so you need to throughly check it before production because I can’t verify it’s accuracy.įrom photos it looks like a compact version of the official Arduino Mega2560, with it’s better Atmega16U2 chip, but the DC power supply has been removed. I can’t find any useful information about the Mega2560 R3 Pro Mini, no datasheet no info no explanation of pinouts, and I don’t have a sample to check.
