The Mega-Tiny Arduino Board was originally intended for use as a controller for DIY keyboards, but it can be used for a variety of other projects, such as robotics, wearables, and IoT devices. Despite its small size, the board has several features that make it attractive for such applications, such as ESD protection on USB power and data lines, a ferrite bead and poly fuse on the USB power line, and a low-pass filter for analog reference.
The Mega Tiny Arduino
The board is built around the ATmega4809 microcontroller, which has 6KB of SRAM, 48KB of flash memory, and 256 bytes of EEPROM. It also includes a mid-mounted USB-C connector for programming and power, along with 23 available I/O pins. The board features a 1.27mm pin spacing and is designed without a voltage regulator.
Overall, the Mega-Tiny Arduino Board is a powerful and versatile tool for creating miniature projects with maximum functionality.
As technology advances, electronic components are becoming smaller, cheaper, and more energy efficient. Integrated circuits, chipsets, and memory modules are just some examples of transistor-based technology that are experiencing this trend. The Raspberry Pi computer, for instance, has computing power comparable to full-sized PCs from a few decades ago and fits in the palm of your hand. The Arduino, a popular platform for hobbyist and professional electronics projects, is also following this trend with the release of the Epi 32U4 board.
The Epi 32U4 board is based around the ATmega32U4 chip, which is unique among Atmel chips for having USB support within the chip itself. This makes it a great choice for projects that involve sending peripheral information to a computer, such as a keyboard or a mouse. The board is also designed with minimal components to eliminate “bloat,” featuring no onboard voltage regulator and just a single LED on pin 13.
One of the standout features of the Epi 32U4 board is its onboard USB-C port. This is a significant perk as more and more devices are shifting away from older USB-type plugs. Additionally, the board’s specifications are available on its GitHub page for anyone interested in producing their own.
Overall, the Epi 32U4 board represents a new level of compactness and functionality in the Arduino platform. Its integration of USB support within the chip itself and onboard USB-C port makes it an excellent choice for a variety of electronics projects.
For those without a 32U4 on hand, it’s still possible to build a keyboard project using other Arduino boards. However, it will require some additional work to implement the same features found on the Epi 32U4 board.
The project’s specifications are also available on this GitHub page for anyone that wants to produce their own
Description:
This miniature marvel is not just limited to DIY keyboards – it can be used for a plethora of projects. Measuring a mere 22.75 x 12.75 x 3.25mm, the Mega-Tiny Arduino Board boasts an impressive range of features that belies its small size. These include a mid-mounted USB-C connector, ESD protection on USB power and data lines, a ferrite bead and poly fuse on the USB power line, a low-pass filter for analog reference, mounting slots, and an impressive 23 available IO (even more than most 32U4 boards!). With a pin spacing of just 1.27mm and no voltage regulator, the Mega-Tiny Arduino Board is the ultimate tool for creating miniature projects with maximum functionality.
Here is a simple example code that you can use to test the Mega-Tiny Arduino Board:
int LED = 4; // Set pin 4 as the LED output
void setup() {
pinMode(LED, OUTPUT); // Set the LED pin as an output
}
void loop() {
digitalWrite(LED, HIGH); // Turn on the LED
delay(1000); // Wait for 1 second
digitalWrite(LED, LOW); // Turn off the LED
delay(1000); // Wait for 1 second
}
This code sets pin 4 as the LED output and toggles it on and off every second. To test this code, connect an LED to pin 4 (with a resistor to limit the current), upload the code to the Mega-Tiny Arduino Board, and watch the LED blink on and off.
Note that this is just a simple example, and there are many more complex projects that you can build with the Mega-Tiny Arduino Board. You can find more example codes and project ideas on the Adafruit website or on various online forums and communities.
