GlowDuino Uno – A better Arduino – A fully Arduino IDE-Compatible Programmable Board

A fully Arduino IDE-compatible microcontroller. The GlowDuino Uno board is our entry into the microcontroller world—the first in the future GlowDuino lineup. Based on the Atmega 328PB, it offers more pins and more functions than a regular Uno board while being backward compatible with existing designs. It offers 24 input/output pins, of which eight can be analog input and nine can be PWM output.

Our goal is to make our designs based on the users’ needs. The GlowDuino Uno offers 1A power output on the 3.3V and 5V lines so that you can connect more things to your board. To help you with connection issues, each standard pin has an indicator LED, so you don’t have to measure to find where the problem is. You can power the board with USB C or 6 to 20V through the power jack for ease of use. If you are using 3.3V-only attachments, you can change the output voltage with a flick of a switch.

Specifications:

  • Chip: Atmega 328PB
  • Clock: 16MHz
  • Memory: 32k
  • SRAM: 2k
  • Max 5V current: 1A
  • Max 3.3V current: 1A
  • I/O current: 40mA
  • I/O pins: 24
  • Analog inputs: 8
  • PWM outputs: 9
  • UART lines: 2
  • I2C lines: 2
  • SPI lines: 2
  • Timers: 5
  • USB connector: Type-C
  • I/O voltage: 5V/3.3V changeable

Documentation: As with almost every design in the maker community, GlowDuino is open-source. Visit our GitHub page for more info about the Uno board: https://github.com/GlowDuino/GlowDuino.

Using the new features:

  • Follow the Software and Installation folder instructions to use the board with the Arduino IDE software.
  • To use the additional four pins, you can refer to them in the program by their name written on the board (22,23, A6, A7). The digitalRead and digitalWrite functions work on these pins as well.
  • Using both serial ports in Arduino IDE works by referring to them as Serial and Serial1 (for serial 0 and 1).
  • To use the second I²C interface, update the IDE package version to 2.0.3 or higher. After that, you can include the Wire1.h library into your sketch and address it as Wire1. Similarly, you can use the second SPI interface as well. Include the SPI1.h library into your sketch and address it as SPI1.

If you do not wish to use new features, you can upload a generic Arduino Uno bootloader to your GlowDuino Uno via the ICSP header. When uploading, use the -f option in Avrdude to disregard the IC signature mismatch. Once uploaded, the microcontroller will behave just like an Arduino Uno would. The voltage level changer switch will still work, but none of the other features will be accessible.

Pin Differences:

Every pin with an indicator LED has a pull-down resistor valued at 665 kiloohms. This means these pins are not floating pins. In our testing, this does not interfere with analog or digital measurements and causes no disturbance when using capacitive touch sensing. However, you cannot use such an analog pin for nondeterministic operations, such as random number generation. For these purposes, you can substitute these pins with either the A6 or A7 analog pins, which do not have pull-down resistors and, as such, are considered floating pins.

Shipping Policy

Please check your SPAM folder to ensure you accept emails from OzRobotics.com to receive your tracking number and download product-related files.

WE SHIP WORLDWIDE: We primarily ship via FedEx, UPS, DHL, and USPS because they’re reliable, fast, and easily trackable. We usually ship within two to three business days after the full payment. Standard delivery generally occurs within 5 to 7 business days after the shipping date. However, the delivery may take about 7 to 10 business days, depending on the shipping destination, logistics, weather conditions, product weight, size, or shipping company distribution structures.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity. To benefit from lower shipping costs for orders with multiple items, please contact us at sales@ozrobotics.com. Our shipping rates are listed clearly on each product page under the SHIPPING tab. Additionally, to see the shipping cost for your country, add the item to the Shopping Cart; you will see the shipping cost based on your Country and Location.

CUSTOMS and TARIFFS: While not all products require a tariff, some products may require a minimal tariff if applicable in your country. The total amount for your order does not include a customs fee/tariff. A tariff belongs to the buyer when applicable. Why don't we add tariffs to the product's retail price? - If all countries deducted the same tariff amount, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount, while some do not even charge. Therefore, we can't add any tariff to the product's retail pricing. Oz Robotics, manufacturing partners, or Suppliers are not responsible for tariffs. Please check the "Made In:" and "Brand:" labels on the product page to see the product's origin. The total amount for your order does not include any duties, import taxes, customs fees, and GST/VAT. The buyer must pay all import duties. If you choose not to pay the tariff and parcel returns, there will not be any refund. Please click here to see more on Tariffs.
