# Maker

> Create custom circuits, prototype your ideas and program with the GPIOs.

**Module:** Basic <Icon icon="seedling" iconType="solid" />

# Features

With this module you can **create circuits and prototype your ideas using the integrated breadboard,** being able to program the circuit with the available pins of the Kode Dot.

In addition, you have the two power buses of the Kode Dot available:

| Voltage | Maximum current |
| ------- | --------------- |
| 5V      | 2A              |
| 3.3V    | 2A              |

## Available pins

You can use the following pins:

| Pin    | Description                     |
| ------ | ------------------------------- |
| GPIO1  | RTC\_GPIO1, ADC1\_CH0, TOUCH1   |
| GPIO2  | RTC\_GPIO2, ADC1\_CH1, TOUCH2   |
| GPIO3  | RTC\_GPIO3, ADC1\_CH2, TOUCH3   |
| GPIO11 | RTC\_GPIO11, ADC2\_CH0, TOUCH11 |
| GPIO12 | RTC\_GPIO12, ADC2\_CH1, TOUCH12 |
| GPIO13 | RTC\_GPIO13, ADC2\_CH2, TOUCH13 |
| SCL    | GPIO47                          |
| SDA    | GPIO46                          |
| U0TXD  | GPIO43                          |
| U0RXD  | GPIO44                          |
| GPIO39 | JTAG-MTCK                       |
| GPIO40 | JTAG-MTCDO                      |
| GPIO41 | JTAG-MTCDI                      |
| GPIO42 | JTAG-MTMS                       |

<Warning>The SCL and SDA pins are of the I2C bus of the Kode Dot, **only they can be used to connect other components to the I2C bus.**</Warning>
