# Openspritzer ## Description OpenSpritzer, an open hardware pressure ejection system for reliably delivering picolitre volumes. Designed for ease of use, robustness and low-cost, the “Openspritzer” is an open hardware “Picospritzer” as routinely used in biological labs around the world. The performance of Openspritzer and commercial alternatives is effectively indistiguishable. It uses Arduino Nano. ## Project Details - **Owner:** adrian95 - **Created:** 9/22/2021 - **Last Updated:** 9/24/2021 - **Visibility:** Public - **Stars:** 1 ## Key Components ### +5V — Power Symbol **Pins:** - P1 ### +5V — Power Symbol **Pins:** - P1 ### A1 — Arduino Nano - Source: https://www.amazon.com/Arduino-A000005-ARDUINO-Nano/dp/B0097AU5OU - Price: 19.10$ **Pins:** - 3V3 - 5V - 5V - A0 - A1 - A2 - A3 - A4 / SDA - A5 / SCL - A6 - A7 - D0 / TX - D1 / RX - D10 - D11 / MOSI - D12 / MISO - D13 / SCK - D2 - D3 - D4 - D5 - D6 - D7 - D8 - D9 - GND - GND - GND - MISO - MOSI - REF - RESET - RESET - RST - SCK - VIN ### D1 — [LED](https://www.flux.ai/jharwinbarrozo/led-tht~gr.md) - Breakdown Voltage: 0V - Series Resistance: 0.42Ω - Emission Coefficient: 3.73 - Saturation Current: 93.2e-12A - Forward Voltage: 1.70 **Pins:** - ANODE - CATHODE ### D2 — [PN Junction Diode](https://www.flux.ai/jharwinbarrozo/pn-junction-diode~z7.md) - Series Resistance: 0.0286Ω - Saturation Current: 300A - Emission Coefficient: 2.00 - Breakdown Voltage: 100V **Pins:** - ANODE - CATHODE ### D3 — [Zener Diode](https://www.flux.ai/lwcassid/zener-diode~oo.md) - Saturation Current: 1.714352819281e-7A - Series Resistance: 0Ω - Emission Coefficient: 2 - Breakdown Voltage: 5.6V **Pins:** - ANODE - CATHODE ### D4 — [Schottky Diode](https://www.flux.ai/lwcassid/schottky-diode~zf.md) - Series Resistance: 2.8Ω - Saturation Current: 3A - Breakdown Voltage: 40V - Emission Coefficient: 2.03 **Pins:** - ANODE - CATHODE ### J1 — [BNC-CONNECTOR](https://www.flux.ai/adrian95/bnc-connector~403.md) - Datasheet URL: https://docs.rs-online.com/029d/0900766b807ba36d.pdf - Manufacturer Part Number: 5-1634556-0 - Part Type: Coaxial Connector - Manufacturer Name: TE Connectivity **Pins:** - P1 - P2 ### J2 — [Barrrel Connector](https://www.flux.ai/jharwinbarrozo/barrrel-connector~ecs.md) **Pins:** - P1 - P2 ### J3 — [Connector 01x02](https://www.flux.ai/jharwinbarrozo/generic-pin-header-01x02-2p54mm-vertical~4uy.md) - Part Type: Connector **Pins:** - Pin_1 - Pin_2 ### J4 — [BNC-CONNECTOR](https://www.flux.ai/adrian95/bnc-connector~403.md) - Part Type: Coaxial Connector - Manufacturer Name: TE Connectivity - Manufacturer Part Number: 5-1634556-0 - Datasheet URL: https://docs.rs-online.com/029d/0900766b807ba36d.pdf **Pins:** - P1 - P2 ### Q1 — [NPN Transistor](https://www.flux.ai/jharwinbarrozo/npn-transistor~hqd.md) - Leakage Current: 1e-13A - Beta / hFe: 100 **Pins:** - B - C - E ### RV1 — [Potentiometer](https://www.flux.ai/jharwinbarrozo/potentiometer~nk3.md) - Package or Case Code: R_POT_PV36W - Resistance: 1kΩ **Pins:** - undefined - undefined - undefined ### SW1 — [DPDT Switch](https://www.flux.ai/jharwinbarrozo/dpdt-switch~33.md) **Pins:** - undefined - undefined - undefined - undefined - undefined - undefined ### SW2 — [SW_SPST_LED](https://www.flux.ai/adrian95/swspstled~njf.md) - Manufacturer Part Number: SW_SPST_LED **Pins:** - 1 - 2 - A - K ### U1 — LM2596S-12/NOPB - Package or Case Code: TO-263 - Part Type: Voltage Regulator - Datasheet URL: https://datasheet.octopart.com/LM2596S-12-NOPB-Texas-Instruments-datasheet-34438175.pdf - Manufacturer Part Number: LM2596S-12/NOPB - Manufacturer Name: Texas Instruments **Pins:** - FEEDBACK - GND - ON_OFF_N - OUTPUT - VIN *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/adrian95/openspritzer~6p6](https://www.flux.ai/adrian95/openspritzer~6p6).* --- *Generated from [https://www.flux.ai/adrian95/openspritzer~6p6](https://www.flux.ai/adrian95/openspritzer~6p6)*
