G30 Module


#1

Ok maybe this has been answered before but why is the G30 SoC more expensive than the G30 TH module? That seems backwards to conventional logic.You have to buy 100+ G30 SoC to get below the price of the TH module… which has the G30 SoC and a bunch of other stuff on a PCB. :slight_smile:


#2

Both products are extremely cheap, no matter which one cost a dollar more :slight_smile:

Still, we need to investigate this


#3

Well it would be nice if the G30 SoC were to drop in price instead of something going up, but I understand if economics don’t fit the model. :slight_smile:


#4

I was just wondering if it is possible to get some empty G30TH-PCBs? I have three lonely G30s lying around, that weren’t used, because I decided to use a G120 with Wifi instead. I’d like to do something useful like putting them on breadboards or something :blush:.

Search the web for lqfp breakout. This maybe a good option.


#6

While it’s not populated, I’ve used this company before for breakout boards. I actually have one of theirs sitting on my bench right now running a long term test of an LTC2495 chip.

You can order them already populated with a digikey part #, they’ll do the soldering and assembly for you. However, I hand tinned my own and reflowed with a reflow station since I already had the IC’s I was going to mount here.


#7

which is the perfect number for a one-off OSHPark PCB order. The Schematic isn’t very complex so I suspect an hour or so in a PCB program would turn that into a decent board. That is, if you didn’t want to look at the other simple breakout options.


#8

Speaking of breakouts, what’s the deal with the two crystal symbols here on the G30 TH schematic?

Q1A and Q1B

Doesn’t it need a single 12mhz crystal resonator? If there’s two there what’s the value on Q1A?

And Q1 = ?? 32k?


#9

I’d say Q1A and Q1B are the same crystals with two different footprints, so a wider variety of crystals can be used, depending on availability and prices on the market.
The 32k-Crystal Q1 is the one for the RTC.
The value of C6-C9 depend on the crystal you use (mostly twice the loading-capacity of your crystal).
