Tiny 2350

Description Show Reviews PIM721 -A postage stamp sized RP2350 development board with a USB-C connection, perfect for portable projects, wearables, and embedding into stuff. While we love the Raspberry Pi Pico we also wanted something smaller and with a bunch more flash on board. Introducing the Tiny 2350 – a teeny tiny powerhouse with the chops to realise truly ambitious projects. Programmable via USB-C, Tiny 2350 comes with4MB of flash storageon board. The board is designed with castellated pads to allow it to be directly soldered onto a PCB (or you can attachpin headersto hook it up on a breadboard or connect things to it directly with wires). We’ve also managed to fit in aprogrammable RGB LED, areset button, aQw/ST connectorfor connecting up I2C devices and some clever circuitry that lets you use the boot button as a user controllable switch. It’s compatible with firmware built for the Raspberry Pi Pico 2 but offers a reduced number of pins due to its size. You can even run MicroPython on it! Features Powered by RP2350A ( Dual Arm Cortex M33 running at up to 150MHz with 520KB of SRAM) 4MB of QSPI flash supporting XiP USB-C connector for power, programming, and data transfer User controllable RGB LED Qw/ST (Qwiic/STEMMA QT) connector for attaching breakouts Twelve IO pins (including four 12-bit ADC channels) Reset and BOOT buttons (the BOOT button can also be used as a user button) On-board 3V3 regulator (max regulator current output 300mA) Input voltage range 3V – 5.5V Programmable with C/C++ or MicroPython Dimensions: approx 22.9 x 18 x 5.8mm (L x W x H, including the USB-C port) Pinout and Schematic Download a printable PDF version Getting Started RP2350 MicroPython builds and examples Connecting Breakouts If your breakout has a Qw/ST connector on board, you can plug it straight in with aJST-SH to JST-SH cable, or you can easily connect any of our I2C breakouts with aJST-SH to JST-SH cablecoupled with aQw/ST to Breakout Garden adaptor. Breakouts currently compatible with our C++/MicroPython build Notes As well as being useful for putting your Tiny 2350 into bootloader mode, you can also use the BOOT button as a user switch. It’s wired to GP23 and active low. The RGB LED is connected to GP18-GP20 and active low (so the on/off state will work in the opposite way to the LED on a Raspberry Pi Pico). You can PWM the pins to dim the LED – check out Tonygo2’s MicroPython example . About RP2350 The RP2350 chip is the Double Quarter Pounder & Fries to the RP2040’s Double Cheeseburger and can have one or more RISC-V burgers instead of either of the M33 ARMs, to stretch the metaphor. In addition to the modern M33 ARM cores, there are sides of: more PIO capability, a variety of low power states for sipping electrons, a whole security system and some sprinklings of specialist digital video circuits to offload DVI/HDMI output. You can expect a tasty boost in performance – our “real world” MicroPython tests are running up to 2x faster compared to RP2040, and floating point number crunching in C/C++ is up to 20x faster. The extra on-chip RAM will make a big difference when performing memory intensive operations (such as working with higher resolution displays) and even more can be added thanks to external PSRAM support. RP2350 comes in two flavours – A (standard) and B (all the pins). The B chip has a stonking 48 usable GPIO pins, including 8 ADCs and 24 PWMs, and features on some of our new products. 0 Reviews Hide Reviews Show Reviews
