![]() 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 - #18 by vanepp 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.Īll available info - Meduino Mega2560 - Google Suche 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 have attached the Interrupt pin on the host shield to the Mega pin D9, and have done the test both with the reset pin attached to the Mega reset pin, and to Vcc, with similar results.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. I need the board to eventually host a USB scanner which takes a fair amount of current. I have used the 3.3V / GND to power the board (markings would indicate it runs on 3.3V, however I understand that the MAX3421 chip works on both 3.3 and 5V. I have used pinout 1 which matches the board I have. Pinout diagram one matches exactly the board I have, and pinout 2 I think is for the 'original'. I have found 2 pinout diagrams for the board, which I have attached. The mini USB host shield (ILS - Mini USB Host Shield 2.0 For Arduino ADK SLR Development Tool ) is from amazon: ![]() The sketch I used is under examples/USB host Library and is called "board_qc", which I am running out of the box. The library I used (USB Host Library 2.0) is located at GitHub - felis/USB_Host_Shield_2.0: Revision 2.0 of USB Host Library for Arduino. Here's some more information on the setup, and the issue at hand. Has anyone has managed to make this combination work? If so I'd love some guidance I also tried the Hid examples with the same result so concluded that I'm doing something basically wrong here. I have tried various recommendations for the interrupt pin, reset pin etc I have currently connected the boards using:Ītmega pin 50 (miso), pin 51 (mosi), pin 52 (sclk), and pin 53 (SS), and the power pin of course. Having read many posts I am currently no further (the hair pulling stage!) I then (just for interest) tried the CircuitsAtHome qc sketch and got the following message: The message coming back from the serial port is 'OSC not started'. I have connected a DuinoFun Mini USB host shield to my Elegoo ATmega 2560, running some basic example code from Oleg's USB Host 2.0 library. As a newbie I'm sure this is basic, but I've been at this a couple of days without success.
