Simblee BLE Module - RFD77101

The Simblee BLE Module is a small Arduino-programmable Bluetooth 4.0 (BLE) module allowing you to get started playing with IoT (Internet of Things). The RFD77101 is a high performance, professional grade Bluetooth® Smart radio transceiver equipped with a built in ARM Cortex M0 microcontroller (with 128KB of Flash and 24KB of RAM, no EEPROM, running at 16MHz) that can be programmed using the simple-to-use Arduino IDE using Simblee extensions. Unlike other IoT offerings, Simblee integrates the GUI description code with the Arduino firmware running on the module.

The tiny RFD77101 module features 45-pin LGA 0.5mm pitch pinout with a 3ms signal latency and 10us accuracy. The Simblee module requires an operating voltage of 1.8V to 3.6V and is capable of communicating at an adjustable physical range from a few inches to hundreds of feet. Users can create sketches to run on their Simblees using the Arduino IDE. These sketches can include user interfaces, which can be displayed on the user's smartphone or tablet, and which can be used to monitor the Simblee's inputs and control its outputs.

Simblee BLE Module - RFD77101 Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    So this is a Cortex-M0-MCU PLUS a BLE-Module PLUS an antenna, right ?

    So I do not understand why this is compared here with any cheap $3-Bluetooth-Modules from China (?)

    • caseyh / about 8 years ago / 1

      You are paying for a complete, stand alone module that is easy to use with FCC and Bluetooth certification in quantities of 1. There are similar solutions without an antenna + ARM that price in about half of this. Seems reasonably competitive.

      • Pikopiko / about 8 years ago / 1

        Yeah but there are other modules out there that are complete solutions that are still much cheaper than this. I have been playing around with Anaren's A20737 (Has micro, flash, antenna and radio). Had some pretty good success getting started with it and looks like I can get their module for about 12 dollars on octopart. This seems awfully pricey.

  • caseyh / about 8 years ago / 2

    Can someone at Sparkfun put this on a scale and tell me how much it weighs?

  • Member #227523 / about 8 years ago * / 2

    Very interesting. Is it perhaps also possible to access other data from the smartphone/tablet, like accelerometer/gyroscope values?

  • Member #480079 / about 8 years ago / 2

    This is a really cool module, but what a horrible price... Too bad these aren't more like $3/each. $19.95 isn't even practical.

    • $3? Here is your $3 blue tooth. Try to fit that in the same form factor. It comes with an FCC ID.

      • Member #480079 / about 8 years ago / 1

        This page still shows 99 in stock which is the same as yesterday. I'm not the only person that thinks the price is too high. Also considering their big marketing push, these should have flown off the shelf (if the price was right).

        Thanks for the eBay link. I bought 10 of them!

      • Member #505321 / about 8 years ago / 1

        Wait --- this $3 thingy is REAL Bluetooth, not BLE? What sucks is all these BLE stuff. No streaming audio..... The only thing I use Bluetooth for is audio.

  • Member #123707 / about 8 years ago / 2

    Is it bad that I want to make a clunky bracelet as a beowulf cluster with these things?

  • Member #347862 / about 7 years ago / 1

    How can this be soldered

    • CF / about 7 years ago / 1

      The easiest way to solder this would be to use solder paste and a hot air rework station, but you could hand solder this with a soldering iron if you design your PCB right.

      The pads around the chip could be soldered by hand but the 4 pads in the center are going to be tricky. If I were doing it, I'd put some large vias directly under each pad and then use enough flux to wick the solder through the via and to the underside of the chip.

      If you have a hot air rework station and a soldering iron, this technique would work as well.

    That hall sensor , can be used to measure the speed of my bike ??

  • Member #834936 / about 8 years ago / 1

    Que, sensor hall, puedo usar para medir la velocidad de mi bicicleta??

  • Member #823876 / about 8 years ago / 1

    Is this module only a bluetooth module or is it a programmable arduino with bluetooth?

  • Member #822338 / about 8 years ago / 1

    Can this be used as a normal bluetooth module? Just uart/spi commutation, like any other bluetooth module. They seem so obsessed with IoT, and I kinda get it, but in some applications I need separate microcontroller anyway, and this gives a bluetooth in tiny form factor, great for some projects.

  • RobotRacer / about 8 years ago / 1

    Is this part in the SparkFun Eagle Library?

  • DustinWoods / about 8 years ago / 1

    It irks me a bit that to create GUI controls on your phone, you need to write them in Arduino on to the chip. Which is then transmitted to the phone when connected. It's novel, and makes it quicker to get up and running, but it means Simblee is not something you would want to use in production. Bummer.

  • stcarlso / about 8 years ago / 1

    This page seems to have a slightly suggestive spelling error in the description...

  • SpockNInja / about 8 years ago * / 0

    This looks very nice! I intend to buy at least one, if only to reverse engineer the firmware to import onto my own NRF51822 hardware. I admit the price point is a bit daunting, especially considering that the hardware is nothing special. However, seeing as it's the first product of a startup, I would expect the price to go down after a while.
