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.
lo necesito urgente y esto no llega nunca
Hi, this sounds more like a shipping related question than a review of the product. I recommend contacting our customer service at firstname.lastname@example.org if you have further questions about your order.
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
The current output pin is always at 0.00V. Voltage pin works ok. I tested it with both the autopilot telemetry and a multimeter. The autopilot works ok but no matter how much current I input, it always displays CERO volts. I checked for possible false contacts but it looks and works ok (tested each pin for continuity with multimeter). I guess this one is faulty…
Sorry to hear you’re having issues with this breakout. If you contact our tech support team, they can help you resolve them.
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
I connected this up and it was simple and works great. Only draw back is pixhawk won’t register a current draw u Der 3 amps but once the motors are running it’s right on. I will advise instead of soldering the 3 sensors wires to this current sensor you should spend $2 on a pin header. Straight or angled pins. Then you can plug a 3 wire servo plug right onto it. 3dr sells 15 pin df13 connectors with servo plugs on the other end. Like the telemetry cable for apm. Well you can pull the pins out of that plug, insert 3 of them into the plastic plug for pixhawks power and the the other end each connector will slide right into a servo plug. That’s what I did and I was able to make the cable with a servo ug on one end for plugging onto the pin header I installed on this sensor and the other end had the df13 plug pixhawk uses with the other end of those 3 wires. So no soldering or anything.. to make the cable you just need a apm telemtry\osd cable and the. Pop the pins out of the plugs and reinsert them into a servo plug on 1 end and pixhawks power plug on the other.. that made installing this sensor a piece of cake..
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
We have modified all our quad and hex copters to 6s lipo. These units are rock solid and easy to integrate.
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.. :)
