That may be true, but what happened to vendor loyalty. I find many things cheaper than at SF but I like to shop at SF :)

Just in case anyone else sees this and thinks it’s odd, it’s because the Wire library used here only supports a 32 byte buffer
The answer to this quandary is the 24LC256 chip. Each chip is an I2C 256k EEPROM, and supports having multiple chips on the same line. So you can have 1 VCNL4000 tied to a 24LC256, and multiple 24LC256 on the same I2C bus. The 24LC256 supports chaining of up to 8 chips…so 8 I2C devices on the same bus.
Just an FYI…searching for 24LC256 shows no results, might want to update the search index…unless you have a policy to not list chips directly :)

While the size of this board is awesome, the foundation of it is simply inadequate. I found that if I press on the board I will get connections where there should be none, and no connection where there should be. I had a simple LED on the board being flashed by an Arduino as a test. I got no response from the LED unless I put pressure on the board, and then when I released the pressure, the LED stopped flashing.
I like the size of this but will have to take it apart and fix it down to a better base or I simply cannot rely on it at all.

I’m trying to hook one of these up to an XBee Series1 Pro(Coodinator) to print responses from remote XBees(Endpoints) but get what looks like very dim Japanese characters. Has anyone tried this, or seen any articles on such?
I’m using the new XCTU software to test sending the following API frame, which should tell the device to show the splash screen:
7E 00 0D 00 01 00 13 A2 00 40 53 5F F1 00 FE 1E 4A
Thanks for any info.
