Turn Your Raspberry Pi into a “Smartphone” or Cellular IoT Gateway with PiTalk 3G HAT (Crowdfunding)

December 11th, 2017 9 comments

The Raspberry Pi boards are used in a countless number of projects, and some of those turn one of Raspberry Pi boards into a (thick) smartphone powered by Linux. The first one was probably PiPhone based on Raspberry Pi 1 Model B, and other followed suit such as TyTelli based on Raspberry Pi Model A+, and more recently ZeroPhone powered, as its name implies, by Raspberry Pi Zero board.

UK based SB Components Ltd is offering another option with their PiTalk HAT based on a Quectel 3G UMTS module, and kits adding a 3.2″ to 5″ display, an optional camera, and/or Raspberry Pi 3 board.

PiTalk Camera Kit

PiTalk board specifications:

  • Cellular Connectivity
    • Quectel UC15 3G/2G UMTS/HSDPA and GSM/GPRS/EDGE module with up to 3.6 Mbps download, 384 Kbps upload
    • SMA antenna connector
    • Push push SIM card holder
    • Voice, SMS and data support
  • Audio – 3.5 mm audio jack, speaker and mic support via unpopulated headers
  • USB – 1x micro USB port for comm., 1x micro USB port for power only
  • 40-pin Raspberry Pi A+, 2/3, Zero/Zero W compatible header
  • Expansion – 2-pin ADC header
  • Misc – On/off switch; Status & “Netlight” indicators
  • Power Supply – 5V via header or micro USB port

Pi Talk HAT

The board can be controlled with Python code, but the company did not provide any details at this stage. A PiTalk GUI interface to control the board will also be offered, and the Open Hardware and Open Software logo are shown on the Kickstarter page, but again no detailed information about that part.

PiTalk Software

Somehow PiTalk “smartphone” is supposed to be powered via the RPi’s micro USB port, as there’s no battery provided, but you could always use a power bank, which will make it even bulkier, but should do the trick if you need some portability. Quectel UC15 module comes in three variants: UC15-E for EMEA/APAC, UC15-A for America, and UC15-T for Thailand, but it’s unclear whether SB Components will offer PiTalk with any of the three versions.

PiTalk has launched on Kickstarter with a 10,000 GBP funding target.  Rewards start at 47 GBP ($63) for PiTalk boad and an antenna, but if you need a kit, you’ll need to pledge 65 GBP ($87) and up starting with the 3.2″ LCD kit. Shipping adds 3 GBP to the UK, and 10 GBP to the rest of the world, and you can expect the rewards to ship in March 2018 if the project can be completed on time.

SixFab Launches Raspberry Pi 3G-4G/LTE Base Shield V2 for $31.20

October 20th, 2017 16 comments

Development boards with 4G LTE are still quite expensive, at least compared to 2G or 3G solutions, with for example Wio LTE GPS Tracker board selling for around $100. So when I saw Sixfab introducing a 3G/4G shield for Raspberry Pi 3 for just $31.20 (pre-orders), I first thought it was an incredible deal.

But I soon realized I missed the “base” word in the name, as the shield just includes the SIM card slot, and mPCIe connector where you can connect Quectel’s UC20-G Mini PCle 3G module or EC25 Mini PCle 4G/LTE Module which adds respectively $59 or $89 to the price. That’s still an interesting HAT board, so let’s have a look.

Raspberry Pi 3 + 3G-4G/LTE Base Shield + Quectel EC25-E 4G Module

Raspberry Pi 3G-4G/LTE Base Shield V2 specifications:

  • Clip-in Mini PCIe socket for:
    • 4G/LTE Module (Quectel EC25) up to 150Mbps downlink and 50Mbps uplink data rates, GPS/GLONASS
    • 3G Module (Quectel UC20) up to 14.4Mbps downlink and 5.76Mbps uplink, GPS/GLONASS
  • Micro SIM card socket
  • USB – 1x micro USB port
  • Compatible with 40-pin Raspberry Pi header
  • Power Supply – 5V via micro USB port or external 5V source
  • Dimensions – 65 x 55 mm

The new version improves on the first model for the shield by reducing the area by 25%, removing the need for screws for the cellular module, using a micro SIM card socket on the top of the board, a more efficient power circuit, and removing the DC barrel jack.

While the board is mostly designed to be used with Raspberry Pi 3 board, it can also be used standalone with your computer, laptop, or another development board over the micro USB port. A blog post explains how to make a PPP Internet connection with the shield connected to RPi 3, and you can get supports in their forums.

Hologram Unveils Nova 3G USB Dongle and Python SDK; 200 Raspberry Pi Zero W Kits Given Away to Developers

October 6th, 2017 No comments

This summer I discovered Hologram global cellular IoT SIM card, and since they provided free developer samples with 2MB of monthly data includes, I decided to get one to try it out. I received it a few weeks later, and to my surprise it worked, despite my country of residence having some strict requirements with regards to SIM card registration. The SIM card uses roaming, but with a low fixed worldwide pricing, and does not come with a phone number by default, so maybe that’s why I did not have to register.

The company is now back with Nova, an open source hardware cellular modem certified by OSHWA (ID #US000077). It’s basically 2G/3G USB dongle that’s controlled by Hologram Python SDK, specifically suited to Debian systems like Raspberry Pi 3 or BeagleBone Black. Hackster.io is also involved in the launch with a worldwide contest offering 200 free kits comprised of Nova 3G USB dongle and Raspberry Pi Zero W board for the best project ideas leveraging cellular IoT.

Nova will eventually come in three versions

  • 3G (in production now) – Ublox Sara-U201 module;  Global 3G/2G GSM;  GPRS/GSM/UMTS/HSPA: 850, 900, 1800, 1900 MHz;
  • Cat-M1 (November 2017) – Ublox Sara-R404M module; USA LTE Cat M-1; FDD: 13 (Verizon)
  • Cat-M1/NB1 (Q1 2018) – Ublox Sara-R410M-02B module; Global LTE Cat M-1+ NB; FDD: 1,2,3,4,5,8,12,13,17,18,19,20,25,26,28

All should have the same other interfaces and other specs:

 

  • u.FL Antenna Connector
  • Nano SIM card holder
  • UART GPIO Pads
  • USB Serial
  • Network Status LED; Power LED
  • Fully end certified (FCC, PTCRB, CE, and AT&T)
  • Dimensions – 46mm x 19mm x 6mm (Plugged in PCB);  71mm x 23mm x 9mm (w/ case)
  • Weight – 8 grams

The hardware kit includes the dongle, Hologram global IoT SIM card, a transparent enclosure, 2 Quad-band flexible u.FL antennas, and access to Hologram Developer Tools for modem and data management.

 

The dongle can be controlled using Hologram client tool, or Hologram Python SDK requiring ppp and Python 2.7 packages, and will allow you to send SMS, setup data connection, and more. Any SIM card should work, and it’s not tied to Hologram SIM card. While the company claims OSHWA certifications, the number US000077 is not present (empty line) in the OSHWA certification list yet, and so far, they’ve only released the PDF schematics. However, Python SDK is fully open source and released under an MIT license on Github.

More details can be found in the product page, and Nova 3G kit can be purchased now for $49.

But as mentioned in the introduction, if you have a great project idea, you could also get the kit for free, and possibly another “grand prize” (Apple Watch Series 3)once the project is completed. The contest is opened worldwide (except to US sanctioned countries) with the following timeline:

  • Submit your proposal by October 27, 2017
  • Best project ideas will be selected, and be sent their kit within around 14 days
  • Build and submit your project to Hackster.io by January 5, 2018
  • 8 Grand Prize winners will be announced on January 8, 2018 for four categories: gateway, asset tracking, remote controlling, and remote monitoring.

There are already 135 participants. Good luck!

 

Arduino MKR WAN 1300 & MKR GSM 1400 Boards Launched with LoRaWAN and 3G Connectivity

September 25th, 2017 4 comments

Arduino has introduced two new boards right in time for Maker Faire New York: MKR WAN 1300 with a LoRa radio, and MKR GSM 1400 with a “3.75G” cellular module, both software compatible with Arduino Zero, and in Arduino MKRZero board form factor.

MKR WAN 1300 Board
