The BackPack170 and SMDBackPack170 were both designed to fit onto the back of the readily available 2.4” and 2.8” TFT screens. I was approached by JMan from The Back Shed Forum to see if we couldn’t come up with a similar board that could interface to the 0.96” OLED I2C displays and the small (8pin) SPI modules (also the popular Nokia 5110 modules). The main design criteria was to be approximately the same size as the 0.96” OLED displays which is 27.3mm x 27.3mm.
As there are 2 common pinouts for the OLED modules we initially were going to have jumper blocks to configure the header to suit but after thinking about this, I decided that if I provide two I2C headers, each configured, for one OLED pinout then the other header `could’ be used to drive other devices (LED panel or Keypad etc.). The SPI header was straight forward as it seems that almost all the common small SPI display modules keep to a common pinout. Then I had to provide some communication options and an ICSP header to actually flash the Pic32MX170, whilst it was quite a challenge, I actually managed to get COM1, COM2 and Console headers onto this postage stamp sized board.
Serial BackPack design.
Serial BackPack was primarily designed to be a `slave’ board that mounts onto the back of a 0.96” OLED display module, as such, I expected that data will be sent to it via one of the COM ports, the console, I2C or SPI. However, it is, of course, possible to run Serial BackPack stand-alone but, due to its size, I wasn’t able to provide access to all IO lines but still there are a reasonable number of IO lines accessible, making Serial BackPack still a good choice for many stand-alone applications.
The table lists the IO lines that are used for Serial BackPack, if you chose not to use a particular port then the IO lines allocated to that port will generally be accessible to do other tasks. I provided the p14 header so that SPI(in) is available (allowing all SPI pins to be accessed) in the advent that the SPI header is not used.
All Maximite and MicroMite support is done on The Back Shed forum at:
You will find the MaxiMite Basic author Geoff Graham offering support there also.
All of the Micks-Mites range of items are considered available only for the hobbyist market, and are priced to suit.
(NOTE **** Most smaller quantities of Microblock products will fit into the small package)
All MGB products are manufactured by Mick Gulovsen, and are based on Geoff Graham's PIC Based MicroMite Basic Computer system. These can be programmed in MMBasic and allows for C extensions for fast routines.
The Micromite is a Microchip PIC32 microcontroller programmed with the free MMBasic firmware. These chips cost from $4 to $10 and are available in a variety of packages from 28 pins to 100 pins. When programmed with the Micromite firmware they make a powerful and easy to program microcontroller that is ideal for most hobby projects.
MMBasic is a Microsoft BASIC compatible implementation of the BASIC language with floating point, integer and string variables, arrays, long variable names, a built in program editor and many other features.
Using MMBasic you can use communications protocols such as I2C or SPI to get data from a variety of sensors. You can measure voltages, detect digital inputs and drive output pins to turn on lights, relays, etc. Special features include the ability to use touch sensitive LCD displays, temperature sensors, distance sensors and more.
All support is done via "The Back Shed" Support Forum. These products are very small, so local and international shipping-postage can be done at minimal costs.
Postage costs on these items are $3 for Australia, and $8 for the rest of the world, as they are sent in a small package. You will find further information on the shipping page during checkout. All of these items are posted to you direct from MBG, Hillside, Melbourne, Australia.
Postage is normally default set to standard postage. You will need to set this to a small package, unless instructed by our sales dept. to do otherwise.
In order to get postage cost down to a "One size Fits All" transaction, we have made the minimum shipping cost the price of a Small Package. Please don't be offended if you get your board(s) in a standard Letter. You simply can't post off a $1 board (or a small quantity), add the price of a basic letter stamp cost, and make enough profit for our time and trouble for this transaction. Consider it like a flag fall on a Taxi meter, as it has to cover basic shipping and handling.
