I karangahia ko te B-L4S5I-IOT01A STM32 Discovery kete, kei te hanga huri noa i te miihini hiko STM32L4 + me nga kaitaera, he mea e mau ana (STSAFE-A110), NFC, Wi-Fi me te Nihokikorangi 4.2.
Kei te hiahiatia te X-Cube-AWS v2.0 STM32Cube Expansion Pack noa-ki te tango, he huinga whare pukapuka me nga tauira tono mo nga microcontrollers e mahi ana hei taputapu mutunga - no konei hoki te tauranga o FreeRTOS. Ko te tauranga, e ai ki a ST, he tohu ki te AWS.
Ko te kete roha (maui) nga utanga, ka waatea ana, he mahi tino-haumaru ki te waahanga haumaru i te wa o te tukatuka MCU, i te wa e whakamanahia ana te taputapu TLS ki te kaitoha AWS 'IoT Core', ana i te wa e whakamana ana i te-rangi (OTA ) whakahou i te mana pono o te whakapakoko me te pono. Ka whakamahia te tiwhikete ahurutanga kua tohaina me te rehitatanga AWS 'IoT Core Maha-Puka Rehitatanga'.
"Ma te kohinga whakarahu, ka taea te whakamahi i te kete hei hoahoa tohutoro," e ai ki a ST. "Ko te X-CUBE-AWS v2.0 te whakarite kia tika te whakaurunga o te anga hononga honohono AWS paerewa FreeRTOS i roto i te taiao STM32Cube. Ma tenei ka whakamahi nga kaiwhakamahi i nga FreeRTOS me te STM32Cube me te kore e whakahiato rorohiko. "
Ko te MCU he Arm Cortex-M4 STM32L4S5VIT6 me te uira 2Mbyte, 640kbyte RAM me te whakaterenga whakamuna whakamunatanga.
Ko nga puoro o runga-papa ko:
- HTS221 capacitive mamati whanaunga-haumākū me te pāmahana
- LIS3MDL 3-tuaka aukume
- LSM6DSL 3D whakatere me te gyroscope 3D
- LPS22HB paemita tino
- VL53L0X wa-o-rere me te tohu-tohu
- E rua hopuoro mamati
Mo te whakawhaanui, ka tohaina nga hononga mo nga papa roha he hototahi ki te Arduino Uno V3, me nga papa Pmod.

Ka taea te tango i te peeke roha timata i konei - kia rite mo te kirimana raihana. E waatea ana he tuhinga poto ma tenei whaarangi.
