Hardware Revision History and Known Issues
This user guide is written to provide information about the latest available revision of the board. The following
sections contain information about known issues, a revision history of older revisions, and how older revisions differ
from the latest revision.
4.1
Identifying Product ID and Revision
The revision and product identifier of the AVR-BLE Board can be found in two ways: Either by utilizing the Atmel
Studio/Microchip MPLAB
By connecting a AVR-BLE to a computer with Atmel Studio/Microchip MPLAB
pop up. The first six digits of the serial number, which is listed under kit information, contain the product identifier and
revision.
Tip: The Kit Window can be opened in MPLAB
The same information can be found on the sticker on the bottom side of the PCB. Most boards will have the identifier
and revision printed in plain text as A09-nnnn\rr, where "nnnn" is the identifier, and "rr" is the revision. Boards with
limited space have a sticker with only a data matrix code, containing the product identifier, revision, and serial
number.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The product identifier for AVR-BLE is A09-3314.
4.2
Revision 3
Revision 3 is functionally the same as revision 2, but features a RN4870 BLE module with firmware version 1.40 (part
number RN4870-V/RM140).
In the silkscreen, the part number of the serial flash chip is wrong. It should be SST25PF040C, but shows
SST25P040C.
4.3
Revision 2
Revision 2 is the initial released revision of the board. It features a RN4870 BLE module with firmware version 1.30
(part number RN4870-I/RM130).
