## Pricing

- **Price:** $1.95 (inc GST) — $1.77 AUD, exc GST
- **Quantity discounts:** 25+ $1.68 (exc GST) · 50+ $1.60 (exc GST) · 100+ $1.51 (exc GST)

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 38 today; more stock is typically available with a 8–12 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09446:1` (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/CE09446:1.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

Perfect for when you need to display the time or some simple sensor read-outs.

Includes M2 37mm x 20mm mounting holes to make mounting and viewing easy.

Note: Even though this sensor uses data and clock it is *NOT I2C or SPI,* seperate pins are required and a proprietary library is below.

### Specifications

- Uses the TM1637 chipset to drive the 7-segment Display
- 3.3-5V Logic and Power input
- Display size: 30mm x 14mm (0.5")
- Ships with pre-soldered right-angle headers
 
### Resources

- [Check out this Micropython Library by mcauser](https://github.com/mcauser/micropython-tm1637)

### Examples

#### Raspberry Pi Pico - Micropython

Library: <https://github.com/mcauser/micropython-tm1637>

 ```
from machine import Pin
import utime
import tm1637

# Define pins for TM1637 display module
TM1637_CLK_PIN = 2
TM1637_DIO_PIN = 3

# Initialize TM1637 display object
tm = tm1637.TM1637(clk=Pin(TM1637_CLK_PIN), dio=Pin(TM1637_DIO_PIN))

# Loop to display a count on the TM1637 display
count = 0
while True:
    count_padded = f'{count:04}'  # Add leading zeros to the number
    tm.show(count_padded)  # Update the display with the number
    count += 1
    utime.sleep(1)
