What a surprise!!! The price is too high. Not sure if this module is designed by Sparkfun or their partner.
I made a module based this chip a year ago. This chip is produced by a Chinese company. The chip datasheet is not good enough. I spent much time study on the chip, basically by experiment. The chip does almost everything. So programming is very easy. However, it has its own interface protocol, which makes a little hard for users (just a little). Unfortunately there is no link on this page to the code.
I was thinking about putting my module on Sparkfun for sale. However, I sent mails to them but got no reply.
To my surprise, today I found this module.
No public wish lists :(
