See every part - 12 pins - In 5 projects Drawn live by the editor's own code, at the size you see it. At a glance ## The Motor driver, DRV8833 in brief What it is, and where it sits on the bench. The DRV8833 is TI’s small dual H bridge, on the Adafruit and Pololu-style breakouts and the red kit module: two DC motors from a single 2.7 to 10.8 V supply on VM, which runs the chip too. Each motor has two inputs, AIN1 and AIN2 or BIN1 and BIN2, and two outputs; there is no enable pin. The inputs read high at 2 V and low at 0.7 V whatever VM is, so an Uno’s PWM pins or an ESP32’s 3.3 V GPIOs drive them, and each has a 100 k pull-down. Mokxi models TI’s logic table (both low coasts, one high drives, both high brakes), the SLP pin with its 1 ms wake, which the breakout pulls up so it can stay unwired, the 2.6 V undervoltage lockout, and 0.18 ohm a side in each bridge, so a battery on VM really supplies the motor current. The classic mistake is forgetting the ground shared between the battery and the board. Current limiting, overcurrent and thermal shutdown are not modeled, so FLT never goes low. Family Outputs Pins 12 Pins ## 12 pins Named as the editor names them, so a wire lands where you expect it. Pin What it does VM The motor supply, 2.7 V to 10.8 V. The chip runs from it too. GND Ground, shared with the board that drives the inputs. SLP Sleep, active low. Pulled up on the breakout, so leave it unwired to run. FLT The fault output, open drain. Nothing in a Mokxi circuit trips it. AIN1 Motor A's two inputs. AIN2 Motor A's two inputs. BIN1 Motor B's two inputs. BIN2 Motor B's two inputs. AOUT1 Motor A. AOUT2 Motor A. BOUT1 Motor B. BOUT2 Motor B. How to use it ## How to use the DRV8833 motor driver with an Arduino AIN1 and AIN2 to pins 5 and 6 for the left motor, BIN1 and BIN2 to pins 9 and 10 for the right, VM to the 6 V of four AA cells, and GND shared with the Uno. The motors go on AOUT1 and AOUT2 and on BOUT1 and BOUT2. SLP is pulled up on the breakout, so it can stay unwired. There is no enable pin. Hold one input low and analogWrite the other: that is drive and coast in turn, and the duty is the speed. Swap which input gets the PWM to reverse. Both inputs low lets the motor coast, and both high brakes it, which is what the bumper car does for 150 ms before it backs away from a wall. Part pin Board pin AIN1 Pin 5 AIN2 Pin 6 BIN1 Pin 9 BIN2 Pin 10 VM 6 V battery GND GND The inputs read high at 2 V and low at 0.7 V whatever VM is, so an ESP32’s 3.3 V GPIOs drive a DRV8833 as well as an Uno does.

With a battery on VM the bridges join the analog solve, so the motor current comes out of the pack. ### Not modeled - The current limit and overcurrent shutdown, so FLT never goes low. - Heat. The real chip shuts down when it gets too hot. From DRV8833 motor driver, in full. Projects ## See the Motor driver, DRV8833 in a project 5 built-in projects use it.

Full-size breadboard A real 0.1 inch grid with the rails and the center channel, 63 columns wide. Jumper wires Drag from any pin or hole to any other. Corners snap, and you can drag them. Power A supply rail at the voltage you choose. Ground The other end of every circuit. LED Lights when current flows. Five colors, and the brightness is what your eye would see.

The same board and the same pinout as a Pico, with the CYW43439 on it. The WiFi is simulated (no radio; real internet through the Cloud panel’s switch), and the on-board LED, which hangs off that chip rather than off GP25, is driven through the same path. Everything else is the Pico. Raspberry Pi 4 Model B Raspberry Pi 4 Model B: the 40-pin header, driven by main.py with RPi.GPIO or gpiozero.
