I’ve been really into the nRF52832 lately, a newer chip from the same company as the nRF24LE1 mentioned in the article. It has BLE, and you can find dev boards with all of the IO pins exposed for $5 (sometimes $2.50 on sale) on AliExpress, or impossibly tiny ones with chip antennas (six fit on a dime!) for closer to $15.
I just realized that the ones I have sitting around have roughly 64x the RAM, 32x the storage, and are (VERY roughly, I had trouble finding compatible numbers) 2,000 times as powerful processors. There’s so much more they could be doing!
- snaky 8y agoThat's funny to know every SD card have a MCU with performance of about 100 MHz on board.
- pietroglyph 8y agoIt's amazing where you can find relatively powerful general purpose processors, and all the vulnerabilities that come with that reality. I like this article on the subject: https://www.bunniestudios.com/blog/?p=3554 https://www.bunniestudios.com/blog/?p=3554
