Building and testing a current sensor board, capable of carrying 40A …
↓↓↓ Complete description, time index and links below ↓↓↓
Last time we connected the throttle circuitry to the original motor driver and controlled the propeller speed and direction via an Arduino MCU (link below). In this video we will build a board for the current sensor with the required connectors.
After a recap of the circuit and a look at the layout, we saw and mill the parts. Then we reflow the copper busbars to a perfboard. We proceed to drill the board and solder the parts on. Finally we do some tests of the finished product.
00:00 Intro – board for 40A current sensor and connectors
00:46 Circuit – short recap of the power monitoring section
01:39 Layout – 40A current sensor and connectors board
03:56 Sawing – perfboards and copper plates to size
05:28 Milling – off unused pads from the perfboard
06:07 Pasting – solder paste and attaching copper plates
07:43 Reflowing – the copper busbars onto the perfboard
09:10 Drilling – 42 holes through the perfboard & busbars
13:54 Soldering 1 – all the parts onto the main perfboard
19:36 Testing 1 – voltage drop @ 5A and power loss @ 40A
22:04 Soldering 2 – current sensor breakout with pigtail
23:31 Testing 2 – reference and output voltage 0A to 5A
25:18 Wrap-up – next the MCP3204 ADC basics & details, bye
