Semtech SX1261/SX1262 LoRa Development Kit Now Available for $305

Orange Pi Development Boards

Semtech announced SX1261, SX1262 and SX1268 LoRa chips in January as updates to their current LoRa solutions with a lower footprint, better efficiency, and even longer range.

Mass production and development kits were expected in March 2018, and today I found out Semtech SX1261/SX1262 development kit is sold on Mouser for $305.

SX1261 Evaluation BoardThe SX126xDVK1CAS kit comes with the following items:

  • 2x SX126xMB1xAS RF modules including an  ST Nucleo Mbed board and a touchscreen
  • 2x Mini-USB / USB connection cables
  • 2x 868/915MHz antennas
  • 2x Mini-USB cables
  • 2x touchscreen styluses
  • Read-Me Note

The SX1261/SX1262 LoRa Transceivers offer continuous frequency coverage from 150MHz to 960MHz.

You’ll find information to get started in the user guide. Basically, the two boards will show a menu on the touchscreen with radio test modes, settings and utilities (e.g. firmware update) as well as two demos:

  • DEMO Ping Pong performs a bidirectional range test between the two radio units.
  • DEMO PER performs a unidirectional packet error rate test between user-defined Master and Slave units.

But uf you want to customize the board firmware, you’ll have to checkout Mbed documentation instead with include Hello World sample and a library.

It appears only the SX1262 kit (SX1262DVK1CAS) is for sale right now on Mouser, but you can find the SX1261 kit (SX1261DVK1BAS) on AVNet Europe for 353 Euros.
