# Logomatic v2 Serial SD Datalogger (FAT32)

**Type:** Product page · **SKU:** WIG-12772 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/logomatic-v2-serial-sd-datalogger-fat32.html ([markdown](https://core-electronics.com.au/logomatic-v2-serial-sd-datalogger-fat32.html.md))

The Logomatic v2 takes everything we learned with multiple logging projects over the years and boils it down to an easy to use device, that is now more adaptable than ever! Version 2 incorporates the LPC2148 with microUSB, battery charging, FAT32 formatting, and microSD support. This allows us to use the SparkFun LPC2148 USB bootloader for even easier and faster modification of the firmware. No programmer required!

## Pricing

- **Price:** $114.95 (inc GST) — $104.50 AUD, exc GST

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=WIG-12772:1` (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/WIG-12772:1.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 Logomatic v2 takes everything we learned with multiple logging projects over the years and boils it down to an easy to use device, that is now more adaptable than ever! Version 2 incorporates the LPC2148 with microUSB, battery charging, FAT32 formatting, and microSD support. This allows us to use the SparkFun LPC2148 USB bootloader for even easier and faster modification of the firmware. No programmer required!

The Logomatic v2 uses a USB mass storage stack to appear under any operating system as a flash drive. Logs are created in FAT32 format on the microSD media and can be downloaded quickly over a USB connection by dragging and dropping the text files from the device. The microSD card can also be removed and inserted into a card reader to download the logs.

This board comes with a JST connector to be powered from our line-up of LiPo batteries or other power sources up to 7.5VDC. If you choose to use LiPo batteries, the Logomatic v2 has a built-in charger to charge batteries off USB.

The Logomatic v2 ships with basic serial text and analog logging. Users can easily start with this firmware but are encouraged to modify the firmware for their specific requirements. It’s a truly flexible logger.
