Unsecure PropMod

Well I have had several people say they are interested in my propmod but don't need the code security. So I have built a new module with similar options but with things located in different places and without the epoxy.

The uSD card reader is now on the top. EEPROM and programing header are now on the bottom. I have added a buck/boos power supply to the board and removed the RTC.

It is late so I will post some drawings tomorow.

Check here for info about original propModule


This new module has the following features:
*512k EEPROM
*5MHz Crystal
*Programing Header
*Pin Compatible with secure module except clockout has been replaced with P29
*Price $30US

Options available:
*uSD card reader($4 US)
*buck boost converter takes an input from 1.8V to 5.5V and outputs 3.3V at 0.8A($10 US)


Blank PCB available for $5 US


I need to sell at least 20 of the PCB or full boards to make this product.

Does anyone want one?

    I have attached the top and bottom view of the module.

    *Pin 37 is actually P29

    $41 can

    so far no one else has said they want. I do need to sell 20 min to cover production costs.

    sounds good. if I can sell 40 I will come to the expo and offer free surface mount soldering lessons.

    anyone else want some?

    that is good. Apparently the 2"x0.8" model is to big for some people. So I will also offer a 1"x1" model. no drawings at present but it will have crystal, eeprom and prop only. Physical layout is like cutting the current one in half and placing the cut off pins just outside the existing pins making it an extra 0.1" wider on each side.

    I will panelise them together so the minimum order of 20 total amongst everyone will be along all 3 of my prop mod designs. Price for this new layout will be the same. $5 for PCB $30 assembled.

    Please note this board has no extra options.

    well baring anyone making large orders I will be sending this off to the pcb manufacturer May 11(day after credit card bill printed) it is about a 1-2 week turn around so May 25th for ship date. If I reach 20 orders before that date I will send off immediately.

    Is that quick enough for you?

    I like the idea of having everything in a small package, especially with the card reader. It is unclear to me though if it can be hooked up directly to a battery or if it must be inserted into a board with regulated power. For example, could I just plug in a battery and a couple servos (powered separately) and have a mini robot?

    Recently frying a couple chips has me more concerned with how things are hooked up. smile.gif

    the boards do have a 3.9v zener diode in for short term over voltage protection. The larger module has an optional power supply built in which means you could use it directly with a battery if you get that option.

    I would want the one with that power supply, would I need to add caps? I didn't see any in the diagram - but then that diagram was for the RTC...

    nope all necisary caps are on the board. look at module_u.PNG above Those little squares on the right side with red boarders are the caps and a few resistors needed. they are small but strong.

    As a note the power supply will take any voltage from 1.8V to 5.5V and give 3.3V out.

    Totally missed that! I was looking at the diagram on the other thread.

    Count me in for one, with card reader & power supply.

    sure. what do you need on the board or just the pcb. also full size or new 1x1?



    Also I just figured out flights to get to the expo will be a grand so I can't make it this year.

    I am very much interested in this. I may need 8 in a few months, but I cannot commit to anything right now. This is perfect. It will save me a ton of time.

    That is exactly what the boards where designed for. Simple plug in module to save you the time of designing it yourself and the hassle of trying to solder very small components.

    I don't need exact numbers but it is good to know which designs I should make more of then the others. I have 155 square inches to split up between the different designs.

    Add 2 1x1 unpopulated for me. I've never tried to solder a QFN and figure it's about time to try. Doesn't look too hard.

    sure. if you have a toaster oven with quartz or infrared elements it is pretty easy. Don't believe it possible with a soldering iron though. The only reason I don't want to do the prop galore by hand is with 8 on 1 board it is to easy to mess 1 of the 8 up.


    Would be uch easier if I was using leaded boards. Lead free is not as nice to work with but since I want these to be universally allowed rosh compliant they must be,

    Soldering QFNs with a soldering iron isn't difficult if the pads are extended a bit. Plenty of gel flux and drag soldering works very well.
