 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Ben Semple just passed me on this information from Olimex, and I felt it may assist other DuinoMite users: -----Original Message----- From: SUPPORT OLIMEX Ltd Sent: Friday, 23 August 2013 8:33 PM To: tripmeters Subject: Fw: Duinomite standard power supply capacity Hey Ben, I just tested it empirically. I used Duinomite, powered by 12V external power supply on the PWR jack and then I connected two 10 Ohm resistors on the 5V line at the Arduino-like shield connector. At 12V the power consumption of the bare board was 0.09A and when the load is connected it goes up to 0.24A. I kept track of the 5V after the MC33063 which was constant (around 5.1 Volts) before and after connecting the load. In other words - the 5V rail might provide safely up to 200mA. Best regards, Lub/OLIMEX ============================= This is for the standard DM power supply. Cheers Don... https://www.dontronics.com |

That was timely! My project has reached a point where I was beginning to wonder what the upper limit might be. Thanks for passing that on Don.  |
