![]() Ideal for applications ranging from 40 to 70 amps, this package includes 4 pairs, 8 male, or 8 female of these popular connectors, with a connector weight of 6.1 grams per pair. File:Bobbycar hoverboard throttle breakout schematic. Our connectors are constructed from the highest quality materials to ensure you get the best connection every time, whatever your application.Inspired by the Jan Henrik break-out boards. All configurable via solder-jumpers for quick setup/change. It also adds filtering to the analog signals for voltage/potentiometer based throttle and pull-ups to the I2C-lanes for Nunchuck-throttle. It has master and slave throttle splitting, where one driver board can be turned off without interfereing with the other - allows for 2x2 front/rear or 4x4 drive! This is a PCB I designed to break out the ADC/UART/PPM/I2C signals to make it easier to finish the build. Schematic and pin-out of the hoverboard connections, by NiklasFauth. File:Hoverboard schematic simple reverse.pdf - Simplified schematic the circuit board.File:Hoverboard schematic full reverse.pdf - Full reverse engineered schematic of the classic hoverboard circuit board.UART Serial control via another MCU or directly via terminalĪ rough overview of the components in the system.I2C Nintendo Nunchuck official remote - I2C pull-ups required on SDA and SCL.ADC Analog voltage input via potentiometer - safety pull-down resistors on ADC1 and ADC2 recommended, high frequency filter to smoothen out the voltage.The hacked firmware supports a quite a few different types of control types, either partially or fully emplemented: Dimensions assembled: L57 x W30 x H39 cm.Vehicle upgrade: Small cussion to improve seating comfort.Vehicle base type: BIG New Bobby-Car Red - note that it's the BIG version, easier to put your legs over the front wheel.Cable connectors: JST SM 4-pin and 5-pin 2.54mm pitch.Upgrade: External charger for anything else.Charger: Lithium-ion charger 42V 2A 3-pin connector with built-in fan.Upgrade: Controller can handle 13S (48V), 12S battery upgrade easiest.Battery: Lithium-ion rechargeable 18650-cells, 10S2P 36V 4400mAh 158.4Wh pack with XT60 connector. ![]() Tire type: non-pneumatic rubber tire, road pattern.Motors: 4x direct drive 3-phase brushless electric wheel hub motors (BLDC) with hall effect sensors, 350W nom., 800W peak.Flasher: ST-Link V2 Programming Unit clone.MCU: STM32F103 72MHz ARM Cortex-M3 core.Controller: 2x Hoverboard main boards - 2015 date. ![]()
