# CB2L Wi-Fi Module
*by Tuya Inc.*
[Product page](https://developer.tuya.com/en/docs/iot/cb2l-module-datasheet?id=Kai2eku1m3pyl)
- [General info](../../docs/platform/beken-72xx/README.md)
- [Flashing guide](../../docs/platform/beken-72xx/flashing.md)
- [BkWriter v1.6.0](https://images.tuyacn.com/smart/bk_writer1.60/bk_writer1.60.exe)
Parameter | Value
-------------|-------------------------
Board code | `cb2l`
MCU | BK7231N
Manufacturer | Beken
Series | BK72XX
Frequency | 120 MHz
Flash size | 2 MiB
RAM size | 256 KiB
Voltage | 3.0V - 3.6V
I/O | 9x GPIO, 5x PWM, 2x UART
Wi-Fi | 802.11 b/g/n
Bluetooth | BLE v5.1
## Usage
**Board code:** `cb2l`
In `platformio.ini`:
```ini
[env:cb2l]
platform = libretuya
board = cb2l
framework = arduino
```
## Pinout
![Pinout](pinout_cb2l.svg)
## Arduino Core pin mapping
No. | Pin | UART | I²C | SPI | PWM | Other
----|-----|----------|----------|-----|------|------
D0 | P8 | | | | PWM2 |
D1 | P7 | | | | PWM1 |
D2 | P6 | | | | PWM0 |
D3 | P26 | | | | PWM5 |
D4 | P24 | | | | PWM4 |
D5 | P10 | UART1_RX | | | |
D6 | P0 | UART2_TX | I2C2_SCL | | |
D7 | P11 | UART1_TX | | | |
D8 | P21 | | I2C1_SDA | | | TMS
## Flash memory map
Flash size: 2 MiB / 2,097,152 B / 0x200000
Hex values are in bytes.
Name | Start | Length | End
----------------|----------|--------------------|---------
Bootloader | 0x000000 | 68 KiB / 0x11000 | 0x011000
App Image | 0x011000 | 1.1 MiB / 0x119000 | 0x12A000
OTA Image | 0x12A000 | 664 KiB / 0xA6000 | 0x1D0000
TLV Store | 0x1D0000 | 4 KiB / 0x1000 | 0x1D1000
Network Data | 0x1D1000 | 8 KiB / 0x2000 | 0x1D3000
Key-Value Store | 0x1D3000 | 32 KiB / 0x8000 | 0x1DB000
User Data | 0x1DB000 | 148 KiB / 0x25000 | 0x200000
Bootloader and app partitions contain CRC16 sums every 32 bytes. That results in the actual flash offsets/sizes not aligned to sector boundaries. To simplify calculations, the values shown in the table (extracted from bootloader's partition table) were aligned to 4096 bytes.
