Friday Product Post: RockBLOCKster

Today we theorize what would happen if the B-52s wrote a song about an Iridium SatComm Module.

Welcome back to another exciting Friday Product Post! Today we have a rockin' new SatComm module for you to check out, as well as a new stepper motor for your Shapeoko, and a handy-dandy new rev! Let's see what Nick wants to talk at us about today.

You can watch the RockBLOCK video on its own here.

Three new products for you to think of what to do with!

RockBLOCK Mk2 - Iridium SatComm Module

RockBLOCK Mk2 - Iridium SatComm Module


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.

Stepper Motor - 125 (200 steps/rev, 600mm Wire)

Stepper Motor - 125 (200 steps/rev, 600mm Wire)


Stepper motors are great motors for position control. They can be found in desktop printers, plotters, 3d printers, CNC milling machines, and anything else requiring precise position control. These stepper motors, in particular, are used with the Shapeoko CNC machine and offer 125 of torque and 200 steps per revolution. Additionally, each motor has been equipped with extra long 600mm AWG22 wires, making them ideal for CNC applications. Check out our new assembly video for the Shapeoko below!

FemtoBuck LED Driver

FemtoBuck LED Driver


The FemtoBuck is a small-size, single-output, constant current LED driver. Each FemtoBuck has the capability to dim a single high-power channel of LEDs from 0-350mA at up to 36V, while the dimming control can be either accessed via PWM or analog signal from 0-2.5V. This version of the FemtoBuck is equipped with a small solder jumper that can be closed with a glob of solder to double the output current from 330mA to 660mA.

That's all folks! We'll be back next week for one more post before the Friday Product Post crew goes on holiday break. We are pretty sure, though, that what we have in store for you will light a few idea bulbs. See you next week!

    You know.. I saw the close-up of this board, sitting on that table, and the white table with the holes in it kind of look like a breadboard, which made the actual circuit look REALLY tiny, compared to those "0.1 spaced" holes my brain was seeing.. :-)

  • Nice, can we put GPS on it?

    Curious the decision to make the Femtobuck jump to 660mA and not something more standard like 750mA or 1A?

      Probably ease and bom simplification. Iset is 0.1V/Rset. To achieve a specific value of 750mA you'd need something like a 0.23 Ohm resistor to create a parallel combination of .13 Ohms
