$10-20 SGD / hour

The power management circuit (in attached schematic) is supposed to regulate voltage up/down to 3.3vdc from supplied battery pack (3.7v), but instead outputs voltage around 0.8V. Also there is some issues with the circuit switching the power to the TSL2561 light sensor from the MOSFET at VCC_LS1_R. Ideally looking for someone with decent english languages skills and strong engineering background. Access to Altium a plus for doing quick fixes to schematics.

I am British and a native English speaker. Please check by resume for my electronics background. Unfortunately I don't use Altium. (Just being honest with you) If this is still OK I'll look deeper into your 'problem' Best regards, Paul Burger

Hello, I am Electrical Engineer by profession. I have built many electronic projects and I know what it takes to make the PCB fully functional. One IC may burn up, or may take more current that what is the limit and give faulty results. For more info please see my portfolio and resume on my website. I will be happy to work. Thanks.

Hi, I am an embedded system engineer and have good debugging skills. I have access to altium as well. You would need following for troubleshooting the schematic attached. 1. Multimeter 2. Oscilloscope (could be used in worst case scenario if multi meter fails) However i would like to know where exactly in the circuit you see 0.8V. Feel free to contact for clarifications if any. I will be glad to help. Thanks and Regards, Prateek
