Pretty common on ebay.
Early reports of “crude device” with the circuitry involved seem to me are dispelled and this was the work of more than some “lone wolf” even though it was locally fabricated.

Whew,,, I see a TI part,,, glad it wasnt my employer’s . . .
It’s from the My Little Camel play set.
Is that a cellphone beneath the board on the first pic? Looks like an older flip phone...
Nope, but then again, I'm starting to question all of the pics and reports coming from the MSM........too many contradictions, too many false leads, too many false reports.
I'm thinking the authorities are deliberatly clouding the facts and letting the MSM deliver the disinformation.
So, we’ve identified two electronic components used in the bombing - the battery pack and the ESC motor controller.
The RF receiver that plugged into that motor controller was most likely a 2.4GHz version.
Its pc board had distinctive notched corners used by companies such as Futaba and E-flite.
Whoever bought these items also had to buy a 7.4V NiMH charger (slightly unusual today).
And they also had to buy a 2.4Ghz transmitter, which is fairly bulky and most likely looks somewhat like a gun, so that would probably be in ANOTHER backpack.
And they may have bought one for each bomb to simplify things.
So they started the day out with THREE backpacks/bags.
And they were probably right BETWEEN the two bombing sites.
The range on 2.4GHz RC modules in that area isn’t that great with so many buildings and people - the bomber probably stayed within 500 yards to make sure they both worked.
The rooftop would be ideal from an RF perspective, but I’ll bet the bomber preferred the anonymity of the crowd.
The battery is a Tenergy rechargeable D battery. It was identified and the maker is a SF Bay area maker.
The battery is made for high end remote control planes and helicopters. It is very expensive, with a suggested retail price of $32.99. Then a good ? is why would a Jehadist/Islamofascist killer use one of these when a plain Jane Duracell would work. The battery for the bomb was only needed once.
If they practiced with dummy exlosives, then they might have need an expensive rechargeable battery. If they practiced out side, someone might have seen them.
