When will you all be posting more information about the hardware module? I'm curious about the specifics of the hardware, (basically datasheet stuff for those of us actually designing hardware):
* supported voltages: 5V, 3v3, 1v8, ...?
* module communication: SPI, i2c, TTL serial, etc.
* module programming: sounds like there is a way to load my key on to the module, will that be done through the attached platform? Or will you need a proprietary programmer?
* footprint for the module: not only dimensions, but keep aways (antenna, etc), orientation, etc. And from the website photo looks like there are no mounting holes on the pcb, and those are especially handy when prototyping
* external antenna: I realize this throws a monkey wrench in the FCC cert, but there are going to be applications where an external antenna is going to be a necessity. Any plans for an external antenna module?
* EN pin: the Iq on many of these radios make it necessary to completely disable them for extreme power savings. Be curious how quickly the radio module can cold boot and establish a link with a base station.
As for the network, no mention of communications with the devices, strictly one way? No ability to push updates to sensors in the field?
I'm missing a couple of others, but I'm too braindead to think of them at this hour.
This looks like it could be a huge time saver for those looking to build out sensor networks, I hope for your success!
- pharkmillups 12y agodr, Can send you data sheet on module. Email hello@helium.co - Not sure on 1v8 - SPI / UART - All module and bridge programming happens OTA - We have arduinos for making pocs, the module is currently 19x12mm I believe. - Our next module will have u.fl. (in the works now) - Network goes in both directions. Access from the internet via ipv6. drFritz.xx.helium.io. -You can also communicate to other devices. The other device can be anywhere as long as it's on the helium network and you are allowed to speak to it. shoot us an email, would love to speak more!
- paletoy 12y agoHow is this protocol better than LoRa(by semtech - an old stable company, used by giants like IBM) ,or weightless(standardized protocol) ? Because they are your competitors , not wifi and the like.
- amalag 12y agoSounds like Helium is taking those technologies and adding a bridge?
