Hi,
Do not be impatient ! I think everybody lets Jingxi Zhang answer because he's the author of the project.
Anyway, the simpler way to get an ECG Primer is to buy a STM32 Primer (see other topics to know where) and the components needed to perform the hardware upgrade to do the upgrade following instructions given on the Project page and to download the code.
Regards
Tybos

I have 2 pieces of ECG PCB left and I can give them free for the developers interested. You have to buy the amplifiers and resistors, and solder the SMD components on to the PCB. If more people want the PCB I can order more and having each one share the cost (probably in $10-$15 each, depends on the volume). Are there any other suggestions?

You can buy STM32 Primer at Digikey, Mouser and Avnet. Here is a discussion link for it (STM32 prices by mtuxpe). I checked the availabilities of the STM32 Primer on these sites. Here are the results by today:
Digikey (http://search.digikey.com/scripts/DkSea … 97-6049-ND): Availability: 30. Price US$50.75/each.
Mouser (http://www.mouser.com/Search/ProductDet … SvpA%3d%3d): Availability: 236. Price US$50.75/each
Avnet (https://www.em.avnet.com/pns/home/0,553 … ilter=TRUE): Availability: 23. Price US$33.93/each

Jingxi Zhang thank u for your help
how i can send u the mony for the pcbs
or if you have a complit kit of the pcb and the componnrnt
any way if i buy 20 units what will be the price of the pcb?
can u send me the 2 units u have and i deliver u the mony ?

I also would like to buy one of your ECG boards if you have one available. (Email sent)
thanks!

jingxizhang · 2008-03-06 23:23:27

Hi dbbb and killerwhale,
please send me your shipping address. I will send one PCB to each of you.

Regards,

Jingxi Zhang

Jing,
I sent you an email about buying a PCB from you, but I have not heard back. Did you receive it yet?
thanks!

Hi Killerwhale,
I sent email to you.

Greetings...I noticed that the ECG circuit / schematic and the Bill of Materials do not match with regards to AD instrumentation amp. I will assume actual circuit / schematic calls out the correct IC. patience requested as I am an aeronautics engineer by trade. while I cannot solder smt I would still like to build circuit on protoboard and integrate. clunky I know.

none the less I would like to get the PCB and try my hand at smt work. email is: bpwillis@buckeye-express.com

jingxizhang,

Is it possible to post your board layout file? I looked for it, but didn't see it on here. Thanks!

jingxizhang · 2008-04-04 07:12:45

The Instrumentation amplifier (IA) is AD627BR. The IA is the schematic is correct. However, in the BOM the IA showed in the LibRef column is AD622AR. Since the AD627BR and AD622AR has the same package and footprint,, and AD622AR library was available so I used the AD622AR Lib reference. Please be sure to use AD627BR in your circuit.
Sorry for the confusing.

Hi Jingxi,

Could you please post the gerber file for the pcb?

englere · 2008-04-09 16:18:13

How about if we get a group order for boards? How many people are interested - please post here?

I would be interested in a couple

Hi,
I would be interested in one PCB, is it possible to get one yet?

jingxizhang · 2009-01-07 01:08:10

Hi,
I got some PCBs for ECG Primer. Let me know if you are interested. It is $15/ea plus shipping.

jonno · 2009-02-05 15:28:41

I would interested in a pcb as well.

Hey Jingxi:
I was going through your project and it really interest me. Wondering if I can use your device to create a solution for my parents. Will it be possible to get one of these devices. I can pay for the cost of device. Plz let me know ASAP.

Thanks,
Anub.

hi jingxizhang!
your project is really excellent so that i was interested from the first time i saw it! now i 'm planing to do my graduation thesis about ecg. The ecg project is necessary for me and thus i want to have one! let me know how i can spend the money to you! please mail to me at address: toiyeuvn2348@yahoo.com. Hoping see you soon.

Hi all,
We are interested by your ECG demo and I have one question concerning the schematic.
Why you have a switching regulator to provide a -5V to the AD627 whereas it is possible to use this Op Amp in single voltage. I guess the regulator should add a lot of noise to the ECG signal ?

Best regards.

Dereck · 2011-10-19 13:13:51

ECG/EEG with the MSP430 Microcontroller can suppress substantial part of the ambient noise. Thus, that's not a problem anymore.
