Telink TLSR8232DK32 User Guide 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. r me 3.6 Arduino interface Telink TLSR8232DK32 board is compatible with Arduino standard interface, to 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 s following two cases: cu 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. r 2) The TLSR8232DK32 can also act as Arduino shield daughter board in fo 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. nk FCC statement: This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 1) this device may not cause harmful interference, and 2) this device must accept any interference received, li including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment. Te AN-17121200-E2 14 Ver 1.1.0
