![]() This is a table to translate the Arduino pin names marked on the silk screen into ARV ports, ordered more or less alphabetically:ĪVR ports to Arduino pin names. and they are therefore sometimes labelled by those functions on the Pro Micro.Īrduino pins to AVR ports. Some pins on the AVR can also be used for special purposes such as serial, timer input, PWM output, etc. pin 3 on the Pro Micro is called D0 on the Atmega32u4.Īrduino makes it confusing by not mapping its pin numbers to AVR ports, but this is for a reason. with QMK), you'll have to translate the pin names marked on its PCB to the AVR ones. If you use the Pro Micro outside the Arduino IDE (e.g. The Atmega32u4 has even more GPIO pins (26), which could be available by soldering directly to the microcontroller, but that's not really for beginners. The additional pins are B0 and D5 as described in the ATmega16U4/32U4 data sheet. This way you can wire up a board with up to 100 keys (using the 18+2 pins in a matrix of 10 rows and 10 columns). Just follow my Pro Micro upgrade guide and solder your wire to the pad of the removed resistors of the RX/TX LEDs. However, there are 2 more pins, used by the onboard LEDs, which can be quite easily turned into usable pins. The Arduino Pro Micro has 18 easily accessible pins, that's theoretically enough for a board with up to 81 keys (9*9). With a little hack though, it can drive a keyboard with up to 100 keys. Maximum is 2048 bytes.The Arduino Pro Micro is cheap (~3$) and perfect for small boards (less than 81 keys). Global variables use 446 bytes (21%) of dynamic memory, leaving 1602 bytes for local variables. Sketch uses 6198 bytes (20%) of program storage space. Global variables use 475 bytes (23%) of dynamic memory, Sketch uses 7062 bytes (22%) of program storage space. Arduino bootloader uses up 2048 bytes of Flash.Total Memory usage with u8x8 Library and Rotary Encoder Code Menu Demo Code - Select between menu options.BounceLEDs - Bounce an LED across pins D5-D13 and A0-A3.Uses Rotary Encoder Tutorial - best code is at the ends under "Code For Improved Table Decode".OLED/Rotary Switch Test - Good starting point.If there is no display on OLED, verify OLED appears at expected I2C address with I2C scan at I2C address 0x3C.Board is designed to fit into Aluminum Project Box Enclosure DIY 100*76*35mm - ebay search.Connect with 1:1 cables to 2x10/2x3 Dupont receptacles.Does not have 26 pin of the 2x13 header in the box.I/O pins are on 0.1" grid for easier prototyping.All Arduino pins brought to J5 - 2x13 pin header.Easy to application specific custom I/O cards.Base board has 3 optional BNC (P1-P3) or edge launch SMA (P4-P6) connectors.0.96" 128圆4 (rotated) with rotary switch (installed in SW1 location) below.0.91" 128x32 or so rotary switch (installed in SW1 location) is to the right.Can be mounted to Front Panel of enclosure.Used to download program to Arduino Pro Mini.Adjust voltage for 3.3V or 5V to match Pro Mini voltage before installing jumper.Connect here to use the BNC or SMA jacks on the rear (option).RF filter into Switching regulator board.Uses the inputs jack as RAW power into the Arduino Pro Mini.Jumper to use raw input and not populate the Mini360.Can leave attached to main board until installing in box. ![]() A six pin header can be connected to an FTDI cable provide USB power and communication to the boardĭetachable Human Interface design (HID).When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.There is a built-in LED connected to digital pin 13.These pins support SPI communication, which, although provided by the underlying hardware.Provide 8-bit PWM output with the analogWrite function.See the attachInterrupt function for details.These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.These pins are connected to the TX-0 and RX-1 pins of the six pin header.Used to receive (RX) and transmit (TX) TTL serial data.I/O - 14 digital input/output pins (of which 6 can be used as PWM outputs).Mounts in a standard extruded Aluminum enclosure.Measured 12 mA with 9V input and 3.3V Arduino Pro Mini.On-board DC/DC buck regulator allows 7-23V input.Detachable Human Interface design (HID).7.2 Total Memory usage with u8x8 Library and Rotary Encoder Code.1.2 Detachable Human Interface design (HID).
