You can really get a lot for $4. I just received a PSoC 4 CY8CKIT-049 4xxx Prototyping Kit.
What is a Cypress PSOC? (from their site)
PSoC® 4 is Cypress’s newest ARM-based PSoC, featuring the low-power Cortex-M0 core combined with PSoC’s unique programmable mixed-signal hardware IP, resulting in the industry’s most flexible and scalable low-power mixed-signal architecture.
PSoC® 4 Highlights
- ARM® Cortex™-M0 CPU up to 48MHz
- Up to 32 kB Flash, 4 kB SRAM
- Programmable Analog: Op-Amps, 12-bit 1Msps SAR ADC
- Programmable Digital: Four PLD-based Logic Blocks
- CapSense® Touch Sensing
- Low Power 1.71 to 5.5V Operation
- 150nA Hibernate Mode, 20nA Stop Mode
The interesting part is that it’s a single chip with an ARM CPU, configurable logic blocks and analog goodies all in one!
The IDE is very nice. I’ve played with the other $30 Eval kit but could not resist getting this kit as it’s much more compatible with the breadboard.
I soldered headers into the board for plugging into the breadboard. It’s jus about too wide, if you plug it in like an IC, you have one row on one side and two on the other for connections. I decided to plug it across the power rail on a big breadboard. The power and ground signals are connected with jumpers underneath the board so it’s ready to go. This trick gives me easy access to all the signals. The USB connector hangs off the end just fine for connection back to the PC.
I love the Ardunio but I can see this board supplanting the Ardunio in my projects. The IDE is great to work with and I’m hoping to have source level debugging but I’m not sure that’s possible, will know soon. The other PSoC board I have does do source debugging but this one calls that smaller interface board a USB serial connection, rather then saying it’s a debugger connection…
