Raspberry Pi Killer?

Nope, but this device has twice the RAM and a bit more performance. It's mostly compatible with Pi, but not fully. It is very new and has little ecosystem but can get the job done.


Device Setup

It is easy to install Python and all the libraries required for IoT and some deep learning. I found most instructions worked for Raspberry Pi on this device. It has more RAM which helps on some of these activities.

I downloaded and burned with Etcher a MicroSD image of TinkerOS_Debian V1.8 (Beta version). It's a Debian variant close enough to Raspian for most IoT developers and users to be comfortable. An Android OS is now available for download as well and that may be worth trying, I am wondering if Google will add this device to the AndroidThings supported devices? Perhaps.

One quirk, make sure you remember this: TinkerOS default username is “linaro”, password is “linaro”. Connect to the device via ssh linaro@SOMEIP.

Python 2.7 and 3.4 both work fine on this device, I was also able to install the major NLP libraries including SpaCy and NLTK. TensorFlow installed using the Raspberry PI build and ran without incident. I believe it's a bit faster than the RPI version. I will have to run some tests on that.


Run The Regular TensorFlow Inception V3 Demo

python -W ignore /tensorflow/models/tutorials/image/imagenet/ --image_file /opt/demo/tensorflow/TimSpann.jpg

I hacked that version to add code to send the results to MQTT so I could process with most IoT hubs and Apache NiFi with ease. JSON is a very simple format to work with.

Custom Python to Call NiFi

# .... imports
import paho.mqtt.client as paho
import os
import json

# .... later in the code
    top_k = predictions.argsort()[-FLAGS.num_top_predictions:][::-1]
    for node_id in top_k:
      human_string = node_lookup.id_to_string(node_id)
      score = predictions[node_id]
      print('==> %s (score = %.5f)' % (human_string, score))
      row = [ { 'human_string,': str(human_string),  'score,': str(score)} ]
      json_string = json.dumps(row)
      client = paho.Client()
      client.connect("", 1883, 60)
      client.publish("tinker1", payload=json_string, qos=0, retain=True)

NIFI Ingest


Ingesting MQTT is easy and again that's our choice from the TinkerBoard. I have formatted the TensorFlow data as JSON and we quickly ingest and drop to a file. We could do anything with this flow file include store in Hadoop, Hive, Phoenix, HBase or send it to Kafka or transform it.


So now we have yet another platform that can be used for IoT and basic Deep Learning and NLP. All enabled by a small fast linux device that runs Python.

Enjoy your SBC! I am hoping that they add hats, a hard drive and some other ASUS accessories. Make your own mini Debian laptop would be cool.

The next device I am looking at is NVIDIA's powerful GPU SBCs. There's a couple options from 192 GPU cores up to 256 with smoking high-end specs.

TinkerBoard FAQ


Modified TensorFlow example /models/tutorials/image/imagenet/


Why do u have to install TensorFlow, spaCy, NLTK, twython, numpy -- wouldnt all of those kill the microSD and the raspberry pi? What is Tensorflow doing anyways - i don't read that anywhere in this post.

Spacy and NLTK are for other purposes on the Tinker for NLP / Sentiment Analysis.

TensorFlow is used to analyze images to figure out what the image is.

The device has a camera or can acquire images elsewhere and can process them on the edge before you send to your data lake

Tinker with it's 2GB and decent processor can easily run this.

A 32 gb microSD card is cheap and stores 10x what I need.

These all run very fast and are complete in seconds. That does not kill this box. And it's not a raspberry pi.

we are running inception see here:
