Femto is a tiny 12x12mm Raspberry Pi RP2040 module

Femto Raspberry Pi RP2040 module

Mirek Folejewski has designed the ridiculously tiny Femto module based on the Raspberry Pi RP2040 microcontroller with a size of just 12x12mm, and still including an SPI flash, a crystal, and a few passive components. We’ve previously covered some really tiny RP2040 boards with the Pimoroni Tiny 2040 and Adafruit QT Py RP2040 boards, as well as the RP2040 Stamp module, but the 12x12mm Femto module is about a quarter of the size of 25x25mm RP2040 Stamp. Femto specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB of SRAM Storage – 4 to 64Mbit QSPI flash I/O – 30 GPIO pins, Reset and BOOTSEL signals, etc… exposed through a frame (See below) Misc – Status LED, 12MHz crystal oscillator, decoupling capacitors Dimensions – 12 x 12mm The board is comprised of two parts: the module itself (aka mainboard) with the Raspberry Pi RP2040 microcontroller […]

52Pi CM4 Router Board also features HDMI, 40-pin Raspberry Pi HAT header, and OLED display

52Pi CM4 Router Board

We’ve already seen compact Raspberry Pi CM4 based router boards with two Ethernet ports from DFRobots, Seeed Studio, and MCUZone. 52Pi CM4 Router Board expands on the same principle but also offers HDMI output, a 40-pin GPIO header for Raspberry Pi HAT expansion boards, and a small OLED information display. The board also includes two Gigabit Ethernet, plus the WiFi and Bluetooth connectivity from the Raspberry Pi CM4, and the extra features make the board larger (146x50mm) than competitors. But that makes the platform that much more flexibly, and can be used as a gateways for all sorts of projects thanks to the wide range of Raspberry Pi HAT available in the market. 52Pi CM4 Router Board (EP-0146) specifications: Compatible with Raspberry Pi Compute Module 4 series Storage – MicroSD card slot (only used with Raspberry Pi CM4 Lite) Video Output – HDMI 2.0 port up to 4Kp60 Display – […]
