The 7Semi Mini is designed with advanced users in mind, offering flexibility, affordability, and a compact form factor. It includes only essential components, omitting on-board USB and pin headers to maintain a cost-effective approach. This makes it an ideal option for those seeking a board to permanently integrate into a project.
The 7Semi Mini ATmega328P Board - 5V is a compact microcontroller board featuring the ATmega328P chip. With 14 digital input/output pins (including 6 PWM outputs), 6 analog inputs, an onboard resonator, and a reset button, this board is designed for semi-permanent installations in various objects or exhibitions. It arrives without pre-mounted headers, providing flexibility for connector options or direct wire soldering. Compatible with the Eden Mini pin layout, this board can be easily programmed using the Arduino IDE software. Plus, it comes preburned with a bootloader for hassle-free code uploading, utilizing the original STK500 protocol, eliminating the need for external hardware programmers.
This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The 7Semi Eden Mini also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work.
Pin Definition
RAW For supplying a raw voltage to the board.
VCC The regulated 5 volt supply.
GND Ground pins.
Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the TX-0 and RX-1 pins of the six pin header.
External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt function for details.
PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite function.
SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language.
LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.
I2C: A4 (SDA) and A5 (SCL). Support I2C (TWI) communication
Reset: Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board.
