# Ultrasonic Distance Meter Reference Design wtDA ## Description This circuit is an ultrasonic distance meter based on an ATTiny2313 microcontroller. It uses an HC-SR04 ultrasonic sensor to measure distance and displays the results on an OLED display. The power supply is constructed using a Boost converter (TPS613222A) and a 2-cell AA battery. Additionally, it also includes ISP for programming, RESET and START switches, and LED indicators. #project #Template #projectTemplate #ultrasonic #OLED #arduino #attiny2313 #TPS613222A #ISP #referenceDesign #simple-embedded #microchip #template #reference-design ## Project Details - **Owner:** roman16 - **Created:** 11/30/2024 - **Last Updated:** 11/30/2024 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ ## Key Components ### BAT1 — [BC2AAPC](https://www.flux.ai/vasy_skral/bc2aapc~866.md) - Part Type: Connector - Datasheet URL: https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/1086/BC2AAPC.pdf - Manufacturer Part Number: BC2AAPC - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Name: MPD (Memory Protection Devices) **Pins:** - - [pin 2] - + [pin 1] ### D1 — [BAT60JFILM](https://www.flux.ai/vasy_skral/bat60jfilm~rjz.md) - Datasheet URL: https://www.st.com/content/ccc/resource/technical/document/datasheet/3d/d2/27/1d/20/e3/4d/48/CD00001944.pdf/files/CD00001944.pdf/jcr:content/translations/en.CD00001944.pdf - Manufacturer Name: STMicroelectronics - Part Type: Diode - Manufacturer Part Number: BAT60JFILM **Pins:** - A [pin 2] - K [pin 1] ### IC1 — [TPS613222ADBVR](https://www.flux.ai/vasy_skral/tps613222adbvr~ek.md) - Datasheet URL: https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=http%253A%252F%252Fwww.ti.com%252Flit%252Fgpn%252Ftps61322 - Manufacturer Name: Texas Instruments - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Integrated Circuit - Manufacturer Part Number: TPS613222ADBVR **Pins:** - GND [pin 2] - NC [pin 5] - NC [pin 3] - SW [pin 1] - VOUT [pin 4] ### RED — [LED-THT-3MM](https://www.flux.ai/vasy_skral/led-tht-3mm~34u.md) - Part Type: LED **Pins:** - A [pin 2] - K [pin 1] ### RST — [TS-1088R-02026](https://www.flux.ai/jecstronic/ts-1088r-02026~fo.md) - Datasheet URL: https://datasheet.lcsc.com/lcsc/1912111437_XUNPU-TS-1088R-02026_C455280.pdf - Manufacturer Name: XUNPU - Manufacturer Part Number: TS-1088R-02026 - Part Type: Switch **Pins:** - P1 [pin 1] - P2 [pin 2] ### START — [TS-1088R-02026](https://www.flux.ai/jecstronic/ts-1088r-02026~fo.md) - Manufacturer Part Number: TS-1088R-02026 - Part Type: Switch - Manufacturer Name: XUNPU - Datasheet URL: https://datasheet.lcsc.com/lcsc/1912111437_XUNPU-TS-1088R-02026_C455280.pdf **Pins:** - P1 [pin 1] - P2 [pin 2] ### U1 — [ATTINY2313V-10SU](https://www.flux.ai/adrian95/attiny2313v-10su~0be.md) - Manufacturer Part Number: ATTINY2313V-10SU - Manufacturer Name: Microchip - Datasheet URL: http://www.microchip.com/mymicrochip/filehandler.aspx?ddocname=en590718 - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Microcontroller **Pins:** - GND [pin 10] - PA0/XTAL1 [pin 5] - PA1/XTAL2 [pin 4] - PA2/~RESET [pin 1] - PB0 [pin 12] - PB1 [pin 13] - PB2 [pin 14] - PB3 [pin 15] - PB4 [pin 16] - PB5 [pin 17] - PB6 [pin 18] - PB7 [pin 19] - PD0 [pin 2] - PD1 [pin 3] - PD2 [pin 6] - PD3 [pin 7] - PD4 [pin 8] - PD5 [pin 9] - PD6 [pin 11] - VCC [pin 20] ### US1 — [HC-SR04](https://www.flux.ai/vasy_skral/hc-sr04~afv.md) - Datasheet URL: https://cdn.sparkfun.com/datasheets/Sensors/Proximity/HCSR04.pdf - Manufacturer Part Number: HC-SR04 - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Sensor **Pins:** - ECHO [pin 3] - GND [pin 4] - TRIG [pin 2] - VCC [pin 1] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/roman16/ultrasonic-distance-meter-reference-design-wtda~eo](https://www.flux.ai/roman16/ultrasonic-distance-meter-reference-design-wtda~eo).* --- *Generated from [https://www.flux.ai/roman16/ultrasonic-distance-meter-reference-design-wtda~eo](https://www.flux.ai/roman16/ultrasonic-distance-meter-reference-design-wtda~eo)*
