I'm quite new to the Teensy world, running a 4.0 and the audio shield. I realize many things are different from the chips I'm used to use (Microchip, MSP, XMC4000 etc), so many things I could not answer by crawling the forum - so please help.
First, I need to store some configuration data - less than a 100Byte - and wondered if theres is any built-in capability? Like EEPROM, SerialFlash (btw, how to access the on-board W25Q16-chip?) Not sure if I really need to spend an SD card for this.
Second, I'm looking for an 3.3V adaptor to RS232. I used to smash an x232-IC on a board when needed, but they are all 5V. Any suggestions?
Looking at the many interesting pins on the bottom side of the board, I wonder how those are supposed to get attached to the circuitry. Solder? Pogo-pins? if so, are there any recommendations?
