  • 100% compatible with ARC for PC, Android and iOS
  • incredibly small footprint!
  • 8 digital I/O (servos, switches, buttons, uart, ultrasonic distance, etc)
  • 2 adc
  • energy effecient digital switching power supply
  • amplified audio and speaker for wifi streaming
  • ezrobot camera port
  • i2c connector
  • web interface
  • telnet interface
  • OTA firmware upgradable

Best of all, it's going to be very affordable! a fraction of the cost of the ezb v4 powerhouse. This will be great for small diy robots or iot devices.

Status: hardware is done. Firmware has two minor tweaks to complete. Should see it on the store with the other ezbits (inverted pendulum, neo pixel controller, etc) over the summer:)

Upgrade to ARC Pro

Take control of your robot's destiny by subscribing to Synthiam ARC Pro, and watch it evolve into a versatile and responsive machine.


Fabulous! Do you have the dimensions and specs I would like to design a shell for it?... I assume it's fused in some way?

P.S... I am waiting on the Tiny to upgrade my new inMoov (with a video of new abilities)... It will make my old inMoov Bartender (he always was a bit twitchy) look like the Skynet Cyberdyne model T-70 in comparison to the T-800...:)


Added a picture to demonstrate the size. Jeremie will pickup this thread and post a dimension image with the size of the mounting holes and such...


@DJ Awesome... Thank you... In addition to a shell I am now actually thinking of altering one of inMoov's arm stls to create a cradle to fit the Tiny... Come to think about it in his head as well......:)


Jeremie did an unreal job of packing all that functionality in the small foot print. There's nothing else like it! Look at that thing... It's unreal and super powerful.


Looking forward to the details... I think (especially if it is a good price point) this will prove irresistible to a lot of the hard core arduino "zombies" that up until now have dismissed ez robot mostly due to their illogical cost rational...


SWEET! This would be awesome for micro-bots! Smallest robot building competition anyone?

Great job Jeremie and DJ.


That is going to be incredibly useful. i particularly like the built in speaker pins (always been nervous about soldering my EZ-B) and the built in barrel jack for power (never much liked the Mini deans connector or its position on the bottom of the board).

I assume the digital ports will, like the V4 be unregulated?

Will it also support USB connectivity like the V4 x/2 with the adapter?


  1. yes unregulated digital pins

  2. yes supports the USB adapter

Don't quote me on this, but I'd like to see the price under $30. It's small but there's a lot of hardware on it - which adds up in cost.


Awesome. That is going to be very useful.



Waw that's a cool thing DJ. I was looking for something like that, and already started some experiments with other brands. You made it just in time ! Can't wait to get it !


Hey! The mini EZB finally got here! This is awesome!

I can now mount this little guy up in the brain inside the bubble of my Lost in Space B9 and get rid of the cables running down the neck of the bubble lifter to the EZB mounted below in the torso. This will make the bubble section it's own little robot.

Will this show up and connect to ARC the same way a full sized EZB will?

Is there anyway you can leak out any other specs on this little gem? Voltage input range, Wifi, Power Pin output?

  1. yeah it's wifi

  2. input voltage range is same as ez-b v4

  3. power pin is same as ez-b v4

  4. everything is same as ez-b v4 but it's smaller:)


Sweet. Good things come to those who wait........ Drat, I can't wait. sick


Attached is a photo of the IoTiny dimensions (in mm):

Some addition bits of info:

  • Barrel jack protrudes 5.5mm away from the board and is 10.4mm in height (the plastic body width is slightly less that the 8.99mm dimension, it's ~8.65mm)
  • Mounting holes are 4-40 hardware compatible
  • Plastic hardware is recommended for use near the WiFi antenna (prevents radio interference)
  • Voltage input is recommeded to be externally fuse protected
  • Reverse polarity protection on Voltage input
  • Low voltage battery monitor
  • 3.3V is protected via short circuit & over current protection from the switching power supply
  • Just like the EZ-bv4 the Digital I/O pins are current limited to ~10mA and are 5V tolerant
  • Unlike the EZ-Bv4 the Analog pins are not 5V tolerant (3.3V max)

Oh, and by the way, I'm pretty excited about this too:D


Awesome, thanks @Jeremie... I will start working on some sort of case for it...


No prob @RR, I'm looking forward to what you come up with!


Ah geeze guys you did it again! I'm developing something new, that I struggled to to fit the full sized EZB into. The timing is impeccable....I'll take a dozen when they come in! Fantastic job again...finally the EZB mini!


May I ask what the current draw of this little thing will be? I'm getting creative all up in my head, and need this info to make some designs!


My Minion hack will soon live! Two are built but had no room for an EZBv4. A LoTiny will allow me to do the movement and sound (with existing speaker), and will easily fit. Thanks EZ Robot team (especially Jeremie).



Thanks guys, I really appreciate the kudos!

@MazeHorizonTech sorry I haven't had a chance to respond yet, it's been a busy couple days.

Here's some rough current draw specs for you:

IoTiny connected via WiFi to my laptop about a foot away, 7.4V input, no peripherals connected and no audio: 60mA

Same scenario + Version 1 Camera: 140mA

Same scenario + Version 2 Camera: 120mA

Same scenario (audio enabled) + Version 2 Camera + Music playing: 190mA

Just note that there are more than a few variables that can effect current draw:

  • Having a weak signal may increase current draw due to the WiFi transceiver working harder

  • With a switching power supply, a higher voltage input allows the circuit to run more efficiently so, in turn, current draw decreases

  • The more bass in your music/voice = more current draw

  • Attaching I2C add-ons will draw more current, the amount completely depends on the device connected

  • Adding servos will dramatically increase the current draw, especially under heavy load

  • Adding Analog sensors will also increase current draw but usually it's only a few milliamps for most sensors

Hope that helps!
