Iqela leRaspberry Pi likhuphe i-RP2040 yebhodi-on-chip kunye ne-40nm architecture: Raspberry Pi Pico.
Inkcazo yeRP2040:
- Dual-core Arm Cortex-M0+ @ 133MHz
- 264Kb RAM
- Ixhasa ukuya kuthi ga kwi-16MB inkumbulo yeFlash ngebhasi ezinikeleyo ye-QSPI
- Umlawuli we-DMA
- Izikhonkwane ze-GPIO ezingama-30, ezi-4 zazo zingasetyenziswa njengamagalelo e-analog
- I-2 UART, i-2 SPI kunye ne-2 I2C abalawuli
- 16 amajelo e-PWM
- Umlawuli we-USB 1.1 onenkxaso yemowudi yokusingatha
- 8 iRaspberry Pi I/O (PIO) oomatshini bombuso abanokucwangciswa
- Imowudi yokuqalisa yogcino lwe-USB kunye nenkxaso ye-firmware nge-UF2
I-Raspberry Pi Pico yenzelwe ibhodi yoqobo, engabizi (kuphela $4) yeRP2040. Iqulethe i-RP2040 kunye ne-2 MB yememori ye-flash kunye ne-chip yonikezelo lwamandla exhasa igalelo lombane ukusuka kwi-1,8 ukuya kwi-5,5 V. Oku kuvumela i-Pico ukuba inikwe amandla kwimithombo eyahlukeneyo, kubandakanywa iibhetri ezimbini okanye ezintathu ze-AA ngokulandelelana okanye ukusuka kwelinye. ibhetri ye-lithium-ion.
Iibhodi ezisekwe kwi-RP2040 chip nazo ziya kufumaneka kungekudala kubavelisi beqela lesithathu:
