HI Rena,

wow, thx a lot for the fast quality answer!  Great!!

i read on the www that many people use therefore an Arduino uno, for flashing, do you build something different? I know you are open-source company but i want to give y something back, so is it possible for you to sell your flasher (hardware software)?

Additionally if this is ok for you, please let me know what I have to implement on my pcb for connecting to your "flasher"

for my project, i will use TinyZero, TinyShield_GPS and ASD2201 microSD card schematic and also EPROM

hi,

first of all, big thx for all your work, great!! 

1. Do you flash the ATSAMD21G18A with your "Arduino software" before delivery or can i do this by my own?
Do you provide the software for flashing?

2. Which Oscillator do you use at TinyZero? I only could read 12?! on the schematic's

BIG THX from Austria, and all the best
Bernhard

PS: I want to build a cat gps to spy my cat
