Pab pawg Raspberry Pi tau tso tawm RP2040 board-on-chip nrog 40nm architecture: Raspberry Pi Pico.
RP2040 Specification:
- Dual-core Arm Cortex-M0+ @ 133MHz
- 264 Kb RAM
- Txhawb nqa txog li 16MB Flash nco los ntawm kev mob siab rau QSPI tsheb npav
- DMA tswj
- 30 GPIO pins, 4 ntawm uas tuaj yeem siv los ua analog inputs
- 2 UART, 2 SPI thiab 2 I2C controllers
- 16 PWM channels
- USB 1.1 maub los nrog hom kev txhawb nqa
- 8 Raspberry Pi I/O (PIO) programmable lub xeev cov tshuab
- USB loj-kho khau raj hom nrog firmware txhawb ntawm UF2
Raspberry Pi Pico yog tsim los ua tus thawj, pheej yig (tsuas yog $ 4) board rau RP2040. Nws muaj RP2040 nrog 2 MB ntawm lub cim xeeb flash thiab lub hwj chim muab nti uas txhawb cov tswv yim voltages ntawm 1,8 txog 5,5 V. Qhov no tso cai rau Pico tau siv los ntawm ntau qhov chaw, suav nrog ob lossis peb lub roj teeb AA hauv koob lossis los ntawm ib leeg. lithium-ion roj teeb.
Cov Boards raws li RP2040 nti kuj tseem yuav sai sai no los ntawm cov tuam txhab thib peb:
