Arduino MKR Connector Carrier / ASX00007

TheArduino MKR CONNECTOR CARRIER is the perfect companion for Arduino MKR boards in the Grove ecosystem. Do you have multiple components to connect to your project and prefer to use connectors instead of soldering? The Arduino MKR CONNECTOR CARRIER provides Seeed Studio's Grove connectors to your MKR board.

The MKR CONNECTOR CARRIER board is an essential tool for rapid prototyping. It allows you to quickly and easily connect sensors using Grove connectors. This expansion board allows you to create applications with different Internet connectivity options by simply swapping out the MKR board and making virtually no changes to your code.

All inputs and outputs are supplied with 5 V, and the MKR CONNECTOR CARRIER board provides the proper level shift from 5 V to 3.3 V. The board has a step-down converter that can be supplied with an external voltage of 7 V to 16 V, connected to the VIN of the screw terminal block. The step-down converter feeds the MKR board, which provides 5V and 3.3V outputs, which can also be found on the screw terminal blocks.

The analog Grove connector consists of four standard lines that make up the Grove connector. Two signal lines are commonly referred to as A0 and A1. Most modules use only A0. Often, in base units, the first connector is called A0 and the second is called A1, and they are connected to connectors A0/A1, and then A1/A2, etc. The last connector, labeled A5 A6, is a connector that combines two analog inputs into one connector in accordance with the Grove connector specifications. If a single input is to be used, the A5 wire input is used.

The digital Grove connector consists of four standard lines that go into the Grove connector. Two signal lines are usually called D0 and D1. Most modules use only D0, but some (such as the LED Bar Grove display) use both. Often with basic units, the first connector is called D0 and the second is called D1, and they connect to D0/D1, and then to D1/D2, etc. The last connector, labeled as D5 D6, is a connector that connects two digital I/O into one connector according to the Grove connector specifications. If a single I/O is to be used, the D5 wired port is used.

The serial connector on the board is connected to the MKR board in accordance with the Grove connector specifications. The Grove UART module is a specialized version of the Grove digital module. It uses both pin 1 and pin 2 for serial input and output. The Grove UART connector is labeled in terms of the base unit. In other words, pin 1 is the RX line (which the base unit uses to receive data, so it is an input), and pin 2 is the TX line (which the base unit uses to transmit data to the Grove module).

The TWI connector on the board is connected to the MKR board according to the Grove connector specifications. There are many types of I2C Grove sensors available. Most of them are 5V/3.3V devices.

The Grove I2C connector has a standard layout. Pin 1 is the SCL signal and pin 2 is the SDA signal. Power and ground are the same as the other connectors.
