Description:

This motor driver board for the micro:bit allows two motors to be driven with forward, reverse, and stop control, and allows access to the other pins.

This board provides a simple way to add motor driving capability to a micro:bit. It allows two motors to be driven with full forward, reverse & stop control. It has terminal blocks to connect four input devices and a regulated 3V supply is fed in to the 80 way connector to power the inserted micro:bit.

In this new version, the pins from the micro:bit are now broken out to pads on the end of the motor driver board. These pads can either be soldered onto directly, or they are the correct spacing for our PCB pin headers (see image below for a close up of the new pads).

It is ideal for designs such as buggies (see below).

It includes an integrated edge connector slot for your micro:bit to easily slot into. It also features external connections to the buttons A and B inputs. This allows additional switches to be connected to the motor driver board and the state of these can then be read by the micro:bit.

Get up to speed quickly. Example Microsoft TouchDevelop code and example connections in the datasheet (below).

Features:

• Drive 2 motors with full forward, reverse, and stop control
• Terminal blocks for easy connection of motors and inputs
• 4 inputs (2 analogue inputs and 2 provide external connections to buttons A and B as inputs)

Looking to do more with your micro:bit? Unlock its potential with this pre-built version of our Edge Connector Breakout Board! This breakout board has been designed to offer an easy way to connect additional circuits and hardware to the pins on the edge of the micro:bit. It provides access to all of the micro:bit processor pins allowing a lot of extra functionality to be added. The datasheet (below) includes a helpful diagram explaining the function of every pin on the micro:bit.

This Edge Connector Breakout Board for the micro:bit gives access to all of the important pins on the bottom edge of the micro:bit. 21 pins are broken out in total; providing additional I/O lines, direct access to buttons A and B, the LED matrix outputs and the I2C bus. Please refer to the datasheet below for more details.

The micro:bit pins are broken out to a row of pin headers. These provide an easy way of connecting circuits using jumper wires.

Description:

Using the analog I/O - module RevPi AIO your RevPi base module can be expanded by 4 analog inputs, 2 analog outputs and 2 RTD input channels. This expansion module is connected to your base module by the means of the overhead PiBridge plug. Inputs, RTD inputs and outputs are galvanically isolated to each other. Differential inputs eliminate ground loops.

Analog input range/options: +/- 10 V, 0 – 10 V, 0 – 5 V, +/- 5 V, 0 – 20 mA, 0 – 24 mA, 4 – 20 mA, +/- 25 mA

Analog outputs range/options: 0 – 5 V, 0 – 10 V, +/- 5 V, +/- 10 V, 0 – 5,5 V, 0 – 11 V, +/- 5,5 V, +/- 11 V, 4 – 20 mA, 0 – 20 mA, 0 – 24 mA

The 2 RTD inputs enable temperatures to be measured with high precision from -165°C to +600°C in steps of 0.5°C using common RTDs sensors like Pt100/Pt1000 probes. The probes can be connected directly to the module with 2, 3 or 4 cables.

Just like the digital IO modules, RevPi AIO is protected against disturbances according to EN61131-2 and can be operated between -40 and +50°C ambient temperature and up to 80% relative humidity. It is also protected against static discharges, burst and surge impulses in accordance with EN61131-2 requirements.

The required PiPridge Plug (Item No.: 100204) and a set of 14-pole PCB female connectors (Item No.: 200030) are already included in the scope of delivery of this expansion module.
