Kano Frozen 2 Coding Kit documentation
A flat octagon around 10 cm across. There are four proximity sensors placed equidistant around the outside. There are eight LEDs around the outside and one in the center that light with varying brightness depending on the proximity detected by the nearest sensor. The device connects via BlueTooth. There are some software applications that use the device for interacting with the software. There is one button that when held for three seconds puts the device to sleep. Pressing the button once wakes the device. The device is powered by two AA batteries.

on https://sms-sgs.ic.gc.ca/equipmentSearch/searchRadioEquipments?execution=e1s1&lang=en - The PCB is labeled with:
KANO K4SB V1.0
,P/N: HG-C-RB265C
, and19G2011A
- SOC: Nordic nRF52832 - https://www.nordicsemi.com/products/nrf52832
- PW546A 4-channel switch for I2C and SMBus. Perhaps this allows the SOC to communicate with one proximity sensor at a time?
- The proximity sensors appear to use use IR reflection?
- The 9 LEDS that light with proximity are RGB.
- There is one blue LED that indicates BlueTooth connectivity state.
- The PCB has pads for an un-populated USB connector labeled
USB1
. - There are un-populated through-holes for an 8-pin connector labeled
PROG1
. - Next to
PROG1
are nine pads labeled:CK
BT
TS
US
GD
IO
RT
SO
3V
- The sleep/wake button is labeled
SW1
. - There are four un-populated pads labeled
SW2
. - There are many test pads labeled
TP1
throughTP20
. - Next to the
USB
pads there are two pads labeledVB1
andVB2
.
The nRF Connect
app for Android from Nordic sees the device as Kano-4SB-4c-2e-62
(4c-2e-62
are the last 3 octets in the MAC address) when scanning for devices.

11a70201-f691-4b93-a6f4-0968f5b648f8 | R, N | 4 bytes | proximity sensor values |
- Each of the four bytes indicates the proximity sensor value for one of the four sensors. The value ranges from
00
(object close to sensor) toFF
(no object close to sensor).FF
appears to be around 20 cm distance. Have not yet tested to see if the value changes linearly with distance.
Notification is supported. When enabled the values will be streamed.

- The initial state is all
0x00
. - Writing a few byte changes the first of 20 bytes. Writing
0x01 0x55 0x00 0x55
then reading returns
0x01 0x55 0x00 0x55
0x00 0x00 0x00 0x00

It appears writing any non-zero byte to the first byte will set the byte to
0x01
. Writing0xFF
then reading returns the same result as writing0x01
then reading. -
The next 3 bytes control the varying brightness of the different RGB colours.
Byte | Purpose |
---|---|
0x00 | Setting to non-zero turns the 9 RGB LEDs off. Reading sensor values is unaffected. |

- On new batteries started around
0x5B
, appears to decline with battery use.
Brightness of the 9 RGB LEDS.
- Defaults to
0x19
. - Writing
0x00
then reading returns0x0A
implying this is the lowest allowed brightness. - Writing
0xFF
then reading returns0x64
implying this is the highest allowed brightness. - Does not appear to affect distance of the proximity sensors.
