I need a small circuit and PCB layout designed. Project is to enable control of a small DC motor via I2c /GPIO and provide accurate current measurement. Features- -Interface to master via I2c or GPIO -Directional control of a single DC motor using h-bridge -Current measurement either integrated in H-bridge e.g MC33926 or separate hall-sensor. -A/D conversion of current measurement > 50Hz, >10 bit e.g MCP3424. -Board powered by 24V DC power supply -To include adjustable switching regulator for motor supply voltage adjustable 12-18v -To include regulated 5v supply for Host system (Olimex A20 LIME) Motor 15V DC running current 500mA, Stall current 2A. Stall occurs for 0.1s 300 times per hour. Board will be interfaced to an Olimex A20-LIME([login to view URL]) and can use any pins on GPIO1 connector 10 prototype units will be produced. Interested in offers that include design and manufacture of prototypes.

I have over 35 years experience as an electronic design engineer, please see my profile for more details I believe I could easily implement your requirement using the parts you have suggested I would provide the following milestones:- 1. Circuit diagram as a pdf 2. Items list fully costed using distributers part numbers as an excel spread sheet. 3. Custom PC layout with assembly as pdf for approval. 4. Gerber files for PCB layout 5. A small number of pre-production units assembled and tested I estimate the following price and timescale for each milestone Items 1 and 2 would be £100 and take 2 days Item 3 and 4 would be £100 take another 3 days Item 6 would be approximately £125 for PCB fabrication of 6 blank boards, the parts would probably be around £25 for each board and assembly another £40 per board. For my time to arrange assembly, buy, and kit, I would require £75 This would take about 4 weeks. Delivery cost would be around £15 for post office special delivery All prices exclude freelancers fee. The bid price just reflects items 1 to 4 Best regards Dave Lelievre Poole Dorset
