Hello all,
Posting this entry to verify some properties of the Real Time Clock (RTC).
Downloaded the user manual from
vma301_a4v02
-
In this manual the pins are documented in the overview as:
| Arduino | VMA301 | |----------+--------| | D5 | CE | | D6 | I/O | | D7 | SCLK | | 5V | VCC | | GND | GND | -----------+---------
The pins on the hardware are indicated as:
Suggest to add these pinnames to the user manual.
Please confirm my values are correct!
| Arduino | VMA301 | Pin names |
|----------+--------+-----------|
| D5 | CE | RST |
| D6 | I/O | DAT |
| D7 | SCLK | CLK |
| 5V | VCC | VCC |
| GND | GND | GND |
-----------+--------+------------
- The primary power (VCC = VCC2) is indicated as 5V
And in “Pin Layout” VCC is documented as
“The VMA301 operates from the larger of VCC1 or VCC2.
When VCC2 is greater than VCC1 + 0.2V, VCC2 powers the VMA301.”
I read this as VCC2 can also be by 3.3V as the battery (VCC1) is rated 3V.
Can you confirm this?
Thank you and kind regards,
Bert
