Stuff I design and build and take apart
The LivingWhites adapter doesn’t really have many surprises. The only two notable things are that the entire high voltage side is from ST parts (VIPER16 , 2 x 14NM65N , ST1S10 ) and the other surprise is the other LED not in the manual.
The non surprising part is the CC2530 IEEE802.15.4 chip .
Here is what is inside the LivingAmbiance / SmartLink / LivingWhites (they should really use less of these trademarks) remote
On the left : a TI CC2530 a “Second Generation System-on-Chip Solution for 2.4 GHz IEEE 802.15.4 / RF4CE / ZigBee”
On the right : a Cypress CY8C2044624 a CapSense controller.
The CC2530 has the 2.4 GHz transmitter and reciever and a microcontroller for the wireless protocol. The Cypress chip handles the buttons and probably the LED’s and speaker (the big square on the right). The UX logic can be in any two of the chips.
The PCB has some capsense buttons that are not on the faceplate. I assume the same PCB is used for both the LivingWhites and LivingColors remotes.
