Sensorboard
Sensorboard is an open source PCB design by Cluradev: a 2-layer, 73 × 50 mm board with 22 components (18 distinct parts). It is built around the LM317_SOT-223, SSP7901P33MR. Filed under displays & leds.
This is the Offical Repo of the Clura Enclosure. Here you will find everything that we have ever made. Enjoy! For more details visit our site: clura.dev
Open hardware KiCad 9 designs for a two-board set: an STM32F411-based mainboard that handles power, control and I/O, and a companion sensorboard carrying the gas/smoke sensing front end. The two connect over an RJ45 link.
- MCU — STM32F411CEU6, 25 MHz HSE + 32.768 kHz LSE crystals, SWD header, BOOT jumper - Storage — micro SD card slot, AT24CS64 I²C EEPROM - Power — 12 V input via barrel jack / screw terminal, LM2596 switchers for 12 V and 5 V rails, SY8120B for 3V3, dedicated +5 V servo rail, fuse and reverse-protection diode - I/O — RJ45 to the sensorboard, HX711 load-cell interface…
