Description

Seesaw ATSAMD09 is a universal framework transducer which expands the number of pins for microcontrollers or microcomputers with I2C interface, e.g.Arduino,Raspberry Pi. It extends the board with additional outputs I2C, GPIO, ADC, PWM, etc. The board can reprogram and reconfigure the system so that they have more or less of each pin, as far as they fit to the software ATSAMD09D14. You can, for example, add a UART transducer, which is not, by default, on the Board.

Pins

Pin Description
VIN The supply voltage is 3.3 V, the board has a voltage regulator 3 V - 5 V. It can be powered by voltage from 3.3 V to 5 V.
3Vo Output from voltage regulator 3.3 V, it can consume 100 mA.
GND The ground of the system.
23 / SCL

Clock pin of I2C communication, it has a 10K resistor of 3.3 V.

22 / SDA Data pin of I2c communication, it has a 10K resistor of 3.3 V.
RST Reset.
8,16, 17, 22, 23 The pins can be used as GPIO or NeoPixeloutputs.
16 / AD0 Pin ADDR0. Connected to ground, increases the address I2C with 1.
17 / AD1

Pin ADDR1. Connected to ground, increases the address I2C with 2.

2, 3, 4

Pins can be configured as ADC input.

5, 6, 7 The pins can be configured as PWM outputs.
8 / IRQ

Pin is low, it signals the host of microcontroller that the interrupt occurred.

SWD

Pin connected to SWDIO to program the device via SWD.

SWC

Pin connected to SWCLK to program the device via SWD.

RST

Pin connected to RESET to program the device via SWD.
