⚡2 New Current Sensors added to JSumo!
AN3V 80A (5V Working Voltage) and CC6921B 100A (3.3V Working Voltage) modules.

At this graph , both sensors are connected in series so that the same current flows through them. The signals are sampled using the wing controller interface with an Arduino Nano. For testing, Omega sumo robot with included Mabuchi 775 type high current drive motors is used.

✔️In free air testing, current levels up to 100A were measured.

⚡The robot render we shared yesterday was very well received (thanks!!), so we're sharing new ones with some technical specifications:
This non-magnetic 3kg type sumo robot (Apocalyse), that uses Maxon RE-Max 29 series geared motors, is an attack sumo robot with agile, low COG design. It's drivetrain is very powerful with its high-speed agile maxon motors and soft silicone wheels. Behind the system, the Xmotion Mega control board powers the entire robot.

Soon will be added to Jsumo.com
