SPEBlox (1GBASE-T1) - Tiny Single Pair Ethernet Converter
SPEBlox-Long is a communication device that provides 10Mbps at extremely long cable runs up to 1,000m (1km) over simple twisted pair copper cable.
This technology uses the 10BASE-T1L specification, and this board aims to provide a cheaper and simpler way of achieving reasonably low bandwidth communication over very long cable runs.
SPEBlox-Long is 31mm x 31mm and provides a standard 10BASE-T ethernet connection on Picoblade header (much like our other products). The 10BASE-T1L (single pair ethernet) connection is placed onto a screw terminal for full flexibility of cable types. The board is powered by any voltage from 5-60V and draws around 500mW (0.5W) of power at full operation.
SPEBlox-Long is perfect for the following applications:
No customer configuration is required on SPEBlox-Long, however an STM32 microcontroller is embedded onboard for communication management options.
This board is shipped with the following cables:
10BASE-T1L is a little more sensitive that 10BASE-T or VDSL when it comes to cabling type. We've found it important to use good quality CAT5-E (or higher) cabling with a known differential impedance of 100 Ohms. The general rule is, if the cable comes with a published specification sheet, then it's likely a high quality cable. You do not need to use shielded CAT5-E, though if your environment consists of lost of EMI, shielded cable is better.
Here is a link to the type of cable we use in our 1km test, and here is the test data of that cable.

All our boards are shipped with the required 0.3 meter power and data cables included, so you do not need to purchase extra cables. However if you need custom cable lengths for your application, you can order those here.
