It is included as part of the Zumo 32U4 Robot Kit and built into the assembled versions of the Zumo 32U4 Robots. Assorted through-hole components, magnetic encoder discs, and mounting hardware are included, but the optional LCD is sold separately. ## Pricing - **Price:** $144.95 (inc GST) — $131.77 AUD, exc GST - **Quantity discounts:** 5+ $126.50 (exc GST) · 10+ $122.55 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 27 and Aug 31. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=POLOLU-3144:1` (comma-separated SKU:qty pairs) and share the link. 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/POLOLU-3144:1.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 **New version available!** Pololu have released an updated **Zumo 32U4 OLED Robot** that includes an OLED display with better graphical capabilities than the LCD used by the original Zumo 32U4 robot. The [**Zumo 32U4 OLED Main Board**](https://core-electronics.com.au/zumo-32u4-oled-main-board.html) can be used as a replacement part for a Zumo 32U4 OLED robot, and Pololu recommend using the newer OLED version for new custom robot builds. This original version of the main board will only be available by special order once Pololu's existing stock runs out. This is primarily intended as a replacement part, but it can also be used to make your own Zumo 32U4 robot if you only want a subset of the parts included with Pololu's full kit. The [Zumo 32U4 Robot Kit](https://core-electronics.com.au/pololu-zumo-32u4-robot-kit-no-motors.html) consists of the following: - [Zumo Chassis Kit](https://core-electronics.com.au/zumo-chassis-kit-no-motors.html) - [Zumo 32U4 Main Board](https://core-electronics.com.au/zumo-32u4-main-board-v1-1.html) - [Zumo 32U4 Front Sensor Array](https://core-electronics.com.au/pololu-zumo-32u4-front-sensor-array.html) - [Zumo 32U4 Blade](https://core-electronics.com.au/pololu-zumo-32u4-blade.html) - [8×2 character LCD](https://core-electronics.com.au/8x2-character-lcd-black-bezel-parallel-interface.html) Two [micro metal gearmotors](https://core-electronics.com.au/category/141/micro-metal-gearmotors-with-extended-motor-shafts) and four [AA batteries](https://core-electronics.com.au/rechargeable-nimh-aa-battery-1-2-v-2200-mah-1-cell.html) are also required to complete the Zumo 32U4 robot. This is the **v1.1 revision** of the Zumo 32U4 Main Board. It uses an [LSM6DS33](https://core-electronics.com.au/lsm6ds33-3d-accelerometer-and-gyro-carrier-with-voltage-regulator.html) accelerometer and gyro and an [LIS3MDL](https://core-electronics.com.au/lis3mdl-3-axis-magnetometer-carrier-with-voltage-regulator.html) magnetometer, replacing the LSM303D and L3GD20H sensors on the original [Zumo 32U4 Main Board v1.0](https://core-electronics.com.au/pololu-zumo-32u4-main-board.html). Pololu's [Zumo 32U4 Arduino library](https://core-electronics.com.au/linkurl0J531) can help you write code that will work with the inertial sensors on either revision.
