Kooxda Raspberry Pi ayaa siidaayay RP2040 board-on-chip oo leh qaab dhismeedka 40nm: Raspberry Pi Pico.
RP2040 Faahfaahinta:
- Dual-core Arm Cortex-M0+ @ 133MHz
- 264 Kb RAM
- Waxay ku taageertaa illaa 16MB xusuusta Flash iyada oo loo sii marayo baska QSPI ee go'an
- Maamulaha DMA
- 30 biinanka GPIO, 4 ka mid ah waxaa loo isticmaali karaa sidii qalab analog ah
- 2 UART, 2 SPI iyo 2 I2C kontaroolayaasha
- 16 kanaalka PWM
- USB 1.1 kontaroolaha oo leh taageerada qaabka martida
- 8 Raspberry Pi I/O (PIO) mashiinada gobolka ee la baran karo
- Habka boot-kaydinta ballaaran ee USB oo leh taageero firmware iyada oo loo sii marayo UF2
Raspberry Pi Pico waxaa loo qaabeeyey sidii asli, jaban (kaliya $4) boodhka RP2040. Waxay ka kooban tahay RP2040 oo leh 2 MB ee xusuusta flash-ka ah iyo chip-ka korontada ku shaqeeya ee taageera tamarta gelinta laga bilaabo 1,8 ilaa 5,5 V. Tani waxay u oggolaanaysaa Pico in laga helo ilo kala duwan, oo ay ku jiraan laba ama saddex baytariyada AA oo taxane ah ama hal keliya. baytari lithium-ion.
Guddiyada ku saleysan chip RP2040 ayaa sidoo kale dhawaan laga heli doonaa soosaarayaasha dhinac saddexaad:
