The RockBLOCK Mk2 allows you to send and receive short messages from anywhere on Earth with a clear view of the sky and it works far beyond the reach of WiFi and GSM networks. Maybe you want to transmit weather information from mid-ocean? Or use it to control your robot in the middle of the desert? Perhaps you need to communicate in an emergency, when other networks might not be available? RockBLOCK can help you.

At the heart of RockBLOCK is an Iridium 9602 satellite modem. The RockBLOCK provides the 9602 with an antenna and an 0.1" header with power and data connections. The header includes an FTDI-compatible serial interface that you can connect directly to almost any microcontroller, or via FTDI Basic Breakout to a computer?s USB port. The RockBLOCK requires a 5V supply that can supply 470mA during startup, and 100mA continuously. Sleep mode can reduce this to 20uA. Alternatively you can power the RockBLOCK with a 3.7V Lipo battery that can supply up to 1500mA. See the Developer?s Guide below for more information.

Iridium is the only satellite network that allows transmission of information from any point on Earth ? other networks have no coverage in the polar regions, and have intermittent or no coverage in other marine and land areas. Iridium has 66 satellites in orbit around the Earth, allowing coverage anywhere on Earth 24 hours a day, 7 days a week. No other satellite network has truly global coverage. Messages sent via Iridium take just seconds to reach you, via e-mail or directly to your web-service.

Note: The RockBLOCK does require a monthly rental service to exchange information with the Iridium satellite network. You only pay for months in which you wish to use the RockBLOCK. No annual contract is required. Line rental costs �8GBP (about $12USD) per month and includes access to The CORE management system for managing your devices. The billing system is built into the CORE, and allows you to pay for only what you use. Check the CORE Information Page link in the Documents section below for more information.

Features:

  • Plug and play satellite communication
  • Full 2-way communication system
  • Integrated antenna and power conditioning
  • Truly global operation, using the Iridium satellite network
  • Data arrives via e-mail, or directly to your own web-service

protection plan is easy.
The protection plan worked on my coffee pot. It was just over 14 months and started to leak. I first called amazon and they sent me a link to the protection plan. It was very easy to use. I received a Amazon gift card instead of a replacement. The price of the coffee pot had increased so you will receive the lower option. I did receive the total cost of the pot at the time I purchased it.

It is worth purchasing a Protection Plan on an unfamiliar item
Bought a 3-year protection plan for a nut milk maker machine for $5.99. It was a fairly new kitchen item in our household and we were not familiar with the brand. So, I bought the plan for a piece (peace) of mind. The machine worked nicely for about 18-20 months with daily use until it tripped the circuit outlet. My initial chat with Asurion did not go as I expected due to discrepancy on their end as they see a protection plan for the nut milk maker as a sporting goods valued between $100-$199, not as a kitchen item valued between $30-$39.99. ( I had bought 3 different protection plan on th same day for multiple items purchased on Prime Days). They were looking at a different plan and I was unable to get them to "scroll over" to the appropriate protection plan. I tried again on a different day during the first hour of their contact hours and had a cheerful Asurion agent who was able to find the appropriate kitchen item protection plan. It was a simple and thorough conversation and transaction. I was refunded within hours after I packed up and dropped off the damaged item out to UPS. Moral of the story: Asurion Protection Plan is worth it and contact them at the start of their first day shift, not at the end of their evening shift.
