The Makerverse™ 10-bit R2R Digital to Analogue Converter (DAC) is a simple and effective way to turn a digital signal into an analogue signal - featuring high accuracy 0.1% resistors and an op-amp voltage buffer. To see (and hear!) it produce music and sound effects, see the Makerverse Audio Kit Guide.

This DAC has been specifically designed for connecting to a Raspberry Pi Pico - the pins and labels are arranged to make it very intuitive to connect - but can be driven by any digital circuit you desire.

The Makerverse 10-bit R2R DAC is based on a simple R2R Resistor Ladder which is a great way to study how a DAC works. It has a THD+N (total harmonic distortion plus noise) specification of approximately 60dB - very close to the theoretical limit for a 10-bit converter and capable of reproducing clear audio signals.

The onboard voltage buffer op-amp is a "rail-to-rail" type, allowing for the DAC module to operate from either 3.3V or 5.0V with only 25mV of clipping when the output approaches the supply rails. The true operating voltage range is 1.8V to 6.0V so the DAC module itself is compatible with other microcontrollers.

The digital inputs labelled GP6 (LSB) to GP15 (MSB) form the binary input with the 0 to 1023 input range mapping linearly from 0V to 3.3V with a step size of approximately 3.2mV.

If you are applying this module to a different microcontroller, and don't need the full 10-bit resolution, only the highest numbered inputs need to be connected and unused inputs connected to ground. For example, a 5-bit DAC can be built by driving GP15 to GP11 with digital signals and grounding GP6 to GP10.

Makerverse Overview

Makerverse hardware is designed for makers, by makers. We're making the tools and modules we think are the most useful to electronics enthusiasts and people that just want to get their projects done. As experienced makers ourselves, we're building in the features and design considerations that we find most valuable and have wished for in other modules.

All Makerverse devices are products designed by our team in Newcastle Australia. We manufacture the modules here as well.

Product Comments

Exact shipping can be calculated on the view cart page (no login required).

Products that weigh more than 0.5 KG may cost more than what's shown (for example, test equipment, machines, >500mL liquids, etc).

We deliver Australia-wide with these options (depends on the final destination - you can get a quote on the view cart page):

  • $3+ for Stamped Mail (typically 10+ business days, not tracked, only available on selected small items)
  • $6+ for Standard Post (typically 6+ business days, tracked)
  • $10+ for Express Post (typically 2+ business days, tracked)
  • Pickup - Free! Only available to customers who live in the Newcastle region (must order online and only pickup after we email to notify you the order is ready). Orders placed after 2PM may not be ready until the following business day.

Non-metro addresses in WA, NT, SA & TAS can take 2+ days in addition to the above information.

Some batteries (such as LiPo) can't be shipped by Air. During checkout, Express Post and International Methods will not be an option if you have that type of battery in your shopping cart.

International Orders - the following rates are for New Zealand and will vary for other countries:

  • $11+ for Pack and Track (3+ days, tracked)
  • $16+ for Express International (2-5 days, tracked)

If you order lots of gear, the postage amount will increase based on the weight of your order.

Our physical address (here's a PDF which includes other key business details):

Unit 18, 132 Garden Grove Parade
Adamstown
NSW, 2289
