So, this one might be the cheapest development kit available in the market? I would really appreciate TI, the company which started this trend of making cute little development kits available at lower price. I still have a MSP430 kit having shape and size of a USB thumb drive which had a price tag of $20. I got that one 3/4 years back from a conference for free. The launchpad costed $5. I think, these kits are still among favourites for engineers.Why these boards did not gain enough publicity as Raspberry Pi, Arduino?...may be because of the lack of a bigger or rather a broader community of users, forums? ...and the absence of a pool of available resources, those are easily available for Arduino, Raspberry Pi?
The NXP LPCXpresso boards -- which have been around for a number of years -- have that sort of snap-off layout, i.e., a USB-based debugger on the left and a demo MCU on the right with DIP layout for the signals. However, the LPCXpresso board I have isn't set up for "snap off" -- I'd have to "saw off" with my fine-toothed razor saw.
The LPCXpresso boards are priced in the US$20-30 range depending on which demo MCU is on the DIP side. Usually it's a tiny ARM M0/M0+ like an LPC1100 or LPC800. What drives up the price is that the USB debug SoC is an LPC3154, a serious CPU with 180 MHz ARM926EJ-S, 192KB SRAM, 16KB instruction and data caches, and MMU. Way overkill compared to the tiny USB controller on the Cypress boards.
Interesting note on the LPC3154: it doesn't have any on-board flash memory, so LPCXpresso has to boot up over USB each time you plug it in.
@barfoo0: They are charging $7.50 to ship in US. So real cost of part is $8
I hadn't thought about the postage (shipping and handling) -- although that would apply to other boards also -- but if they are changing $7.40 to ship, then wouldn't the full price be $4 + $7:50 = $11.50? (Where did you get $8 from)
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
