> **Source:** Core Electronics is an Australian maker-electronics retailer and manufacturer based in Newcastle, NSW, run by a team of makers and educators. We design and manufacture our own product lines (PiicoDev, CE originals) and are official retailers for iconic maker and industrial brands including Raspberry Pi, Arduino, Adafruit, SparkFun and DFRobot. Orders ship Australia-wide from our Newcastle warehouse. Prices are in AUD and include GST. Pricing, stock and dispatch on this page are generated from the store's live catalog.

Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE08391:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description 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](https://core-electronics.com.au/guides/makerverse/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](https://en.wikipedia.org/wiki/Resistor_ladder#R%E2%80%932R_resistor_ladder_network_(digital_to_analog_conversion)) 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. **Resources** - [Hardware Repo](https://github.com/CoreElectronics/CE-Makerverse-R2R-DAC-10-Bit) - [Schematic](https://github.com/CoreElectronics/CE-Makerverse-R2R-DAC-10-Bit/raw/main/Documents/schematic.pdf) **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 [![](https://core-electronics.com.au/media/wysiwyg/product_images/Core-Electronics-Original.png)](https://core-electronics.com.au/original) products designed by our team in Newcastle Australia.
