3.2 Download Firmware into TLSR8232DK32
Two connection methods are supported to download firmware into Telink
TLSR8232DK32 board.
1. Method 1: Connect via USB
Make sure a jumper cap is connected on J12 of TLSR8232DK32.
Connect J15 (miniUSB interface) with the USB interface of a burning key (i.e.
burning EVK board) via an USB cable. The miniUSB interface of the burning key is
connected with PC USB via an USB cable.
2. Method 2: Connect via Swire
Connect PIN3, PIN4 and PIN5 of J3 with 3.3V, SWM and GND of a burning key,
respectively.

3.3 Measure power-saving mode current for TLSR8232DK32
To measure current consumption of Telink TLSR8232DK32 board in deep sleep or
suspend mode, please follow the connection steps below:
1) Remove jumper caps from J12 and J13 of TLSR8232DK32.
2) Connect anode (+) and cathode (-) of an amperemeter with anode (+) of 3.3V
power supply and PIN2 of J12, respectively.
3) Connect cathode (-) of the 3.3V power supply with PIN5 of J3.

3.5 Test GPIOs for TLSR8232DK32
Since all GPIOs of Telink TLSR8232DK32 board are already connected to
corresponding pins of headers including J3, J10 (if PB6 and PB7 are not used as external
32kHz crystal output and input), J21, J29 and J31 (please refer to Table 1 or the
schematic), user can directly test GPIO signals on header pins.
3.6 Arduino interface
Telink TLSR8232DK32 board is compatible with Arduino standard interface,
which adopts single-column direct-in female headers (J18, J19, J20, J22) with pin
distance of 2.54mm. The TLSR8232DK32 can be used for development in the
following two cases:
1) By default, the TLSR8232DK32 acts as Host control board by connecting it with
Arduino shield daughter board. In this case, it’s needed to connect four jumper
caps with PIN1 and PIN2 of J33, PIN1 and PIN2 of J34, PIN1 and PIN2 of J35, as
well as PIN1 and PIN2 of J36.
2) The TLSR8232DK32 can also act as Arduino shield daughter board in
combination with Arduino Host control board. In this case, it’s needed to
connect four jumper caps with PIN2 and PIN3 of J33, PIN2 and PIN3 of J34, PIN2
and PIN3 of J35, as well as PIN2 and PIN3 of J36.
FCC statement:
