EduBase ARM Trainer
A FRDM base board for academia |
|
The FRDM-KL25Z module can be mounted directly on the
trainer, you can connect signals from FRDM's female
headers to the trainer I/O bus in anyway you
like to make your experience.
We provides a bridge board to connect all signals
for you. Without it you can use jumpers to connect
signals

* SDA and SCL are selectable for I2C0 or I2C1,
default to the I2C0.
Accessories:
The FRDM does not
come with female headers.
You need to solder them by yourself.
It also does not come with a USB cable. You need to buy
a USB mini B cable if you don't have one.
