> ⚠ Deal is for shelf stock only — any additional stock will be at the normal price.

## Pricing

- **Price:** $31.26 (inc GST) — $28.42 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE08592:1` (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/CE08592:1.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)

## Description

The full-featured ESP32-S2 based development board in a Feather format from Unexpected Maker. The FeatherS2 is a power house, fully souped up with **16 MB of Flash memory** (for firmware and file storage) and **8 MB of QSPI-based external PSRAM** so you can have massive storage buffers.

###  

### 2x LDO Voltage Regulators?

Yup! The first one is for the general operation of the board and the ESP32-S2, RAM and Flash.

The second LDO is for you to use to connect external 3V3 modules, sensors and peripherals, and it has programmable EN control tied to GPIO21 + it’s connected to the deep sleep capabilities of the S2, so if the S2 goes into deep sleep, the 2nd LDO is automatically shut down for you!

### Ships with CircuitPython pre-installed!

The FeatherS2 ships with CircuitPython pre-installed as well as the UF2 bootloader, so you can easily update your FeatherS2 with the latest CircuitPython firmware, whenever you desire.

As newer versions of CircuitPython are released, you are able to update as you require from [ciruitpython.org](https://circuitpython.org/board/unexpectedmaker_feathers2/)

There is also [ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/get-started/index.html) and [Arduino](https://github.com/espressif/arduino-esp32/) support if you prefer coding in C++.
