Introducing the OBD-II UART Adapter for Arduino (with built-in MPU-6050)


the obd-ii uart adapter arduino works data bridge between vehicle's obd-ii port , serial uart of arduino, used reading out data such speed or engine rpm car's ecu computer. dedicated arduino library, extremely simple perform readout on arduino. adapter embeds mpu-6050 accelerometer/gyro/temperature sensor module inside i2c interface. accelerometer can used measuring car's acceleration , steering g-force. gyroscope can used measuing car's orientation without gps.



besides providing obd-ii data access, outpus dc 5v power supply (converted , regulated obd-ii port) arduino , attached devices.

the adapter has standard obd-ii connector can plugged , locked in obd-ii port under dashboard of car. cable comes out adapter , splits 3 connectors @ end, power connector (vcc/gnd), obd-ii data connector (rx/tx) , i2c sensor connector (sda/scl). can connected arduino onboard breakout pins or breakout shield. arduino device tidy in car 1 connected cable.




faqs

q: how adapter powered?
a: adapter gets power 12v dc output obd-ii port.

q: arduino needs power somewhere in car?
a: adapter provides regulated 5v dc output provide power arduino via power connector. arduino can powered connecting power connector (vcc/gnd) arduino's 5v , gnd pins, no power input needed.

q: need can bus shield use adapter?
a: no. adapter retrieves data can bus, can bus shield , convert more complicated can bus interface simple serial uart interface arduino , embedded systems easy access. data connection provided adapter's data connector (rx , tx).

q: how connect adapter arduino?
a: adapter works models of arduino dedicated arduino library , connected arduino connecting adapter's tx arduino's rx (d0) , adapter's rx arduino's tx (d1). if want connect , disconnect adapter arduino effortlessly, it's recommended use common i/o breakout shield or use arduino board breakout pins rx/tx/vcc/gnd.

q: power provided adapter available in car?
a: depends on whether obd-ii port of car still has power after ignition off. cars.

interesting, leaves me couple questions...

1. of standard commercial obd readers can reset "check engine" light - able that?

2. there ability write stuff car's onboard systems can potentially alter way car drives  - stuff changing way cruise control acts on hills, or of other "tuning" functions claimed of aftermarket chips?

my 2010 chrysler t&c minivan has behaviors find obnoxious, not enough justify purchase of 1 of "chips" it, assuming claim...  i'm wondering if there way less money...

thanks,
