SparkFun will be closed Nov 26th and 27th for the Thanksgiving holiday. Orders placed after 2:00pm MT on the 25th will ship out Monday the 30th.
Description: This is a small voltage and current sense PCB. DC current is determined by measuring a voltage drop across a pair of parallel shunt resistors, then converted to a final analog voltage output by the TI INA-169. Voltage sense is accomplished by scaling to 3.3V ADC range by a precision resistor divider.
The PCB is supplied without leads or connectors. The pad sizes are large enough to accommodate 12 gauge heavy duty leads (see datasheet) but care must be exercised in soldering. Smaller gauge leads are considerably easier to solder without creating shorts.
Dimensions: 4 x 15 x 19mm

An excellent electrical design and rugged. excellent value versus performance.
Item works fantastic, but seems to be older version without the cutouts for deans connector. I order two and these do not have cutout for deans connector. So I went back to website and ordered two more based on image showing cutouts for deans plug, but when items arrived these were the previous boards with no cutouts for deans. I now have four of the boards with no cutouts. Please revise your image or stock of these items.
Hi, So sorry for this issue. These actually appear to be the new version. All units appear to no longer include a deans connection cutout like you mentioned. We will absolutely update our photos to reflect this change. Thank you
Wow, they must be making a pretty big margin at this price. Otherwise it is a solid board with accurate readings.
A little tricky to solder 8 AWG wires to the small board
IT WORK VERY WELL THANK YOU
works really well with APM 2.6 and mission planner. they have pre populated setups for the atto’s and it worked exactly as it said, the first time with no screwing around with it. really happy now I can use it on my 6s multi rotors
work perfect with pixhawk. thx
It was easy to assemble and is doing it job without any complaints.
The signal outputs is very close to power connectors. I prefer them to be on the side. Do not solder and re solder again because the pcb material can easily be damaged. Overall it was ok. altought I burned it and have to buy anaother one.. :)
