# Bill of Materials This is a list of components you need to build the OpenTendo NES. You will need some components from the original NES and have to order more modern components. ## From the OEM NES | Reference | Qty | Part | Description | | --------- | :-: | ---- | ----------- | | U5 | 1 | **NTSC:** RP2C02
**PAL:** RP2C07 | PPU | | U6 | 1 | **NTSC:** RP2A03
**PAL:** RP2A07 | CPU | | U10 | 1 | 3193A | CIC | | P2 | 1 | Connector | 48 pin expansion port | | P6 | 1 | Connector | 5 pin connector for the power/reset breakout board | ### Alternatives | Reference | Qty | Part | Description | | --------- | :-: | ---- | ----------- | | P2 | 2 | [PPPC241LFBN-RC](https://octopart.com/pppc241lfbn-rc-sullins-271073)[1] | 24 Pins Header Connector 0.100" (2.54mm) Through Hole | > [!NOTE] > [1] If you don't want to use the OEM expansion port, you can replace it with a header pin connector or not put anything at all. OpenTendo should still work without the expansion port. ## What to buy We recommend using Octopart's [BOM tool](https://octopart.com/bom-tool/) and import the [BOM.csv](BOM.csv). This tool makes ordering from multiple Octopart's authorized distributors (Digikey, Mouser, etc.) easier. ### Resistors | Reference | Qty | Part | Description | | --------- | :-: | ---- | ----------- | | RA1 | 1 | [4613X-101-103LF](https://octopart.com/4613x-101-103lf-bourns-1656444) | 10k Ohm ±2% 200mW Bussed 12 Resistor Array 13-SIP | | R1 | 1 | [RNF14FTD1M00](https://octopart.com/rnf14ftd1m00-stackpole+electronics-19224733) | 1M OHM 1% 1/4W | | R2, R12 | 2 | [CF18JT510R](https://octopart.com/cf18jt510r-stackpole+electronics-19205768) | 510 OHM 5% 1/8W | | R3, R4 | 2 | [CF18JT100R](https://octopart.com/cf18jt100r-stackpole+electronics-19205641) | 100 OHM 5% 1/8W | | R5 | 1 | [CF18JT220R](https://octopart.com/cf18jt220r-stackpole+electronics-19205701) | 220 OHM 5% 1/8W | | R6 | 1 | [CF18JT47K0](https://octopart.com/cf18jt47k0-stackpole+electronics-19205759) | 47K OHM 5% 1/8W | | R7, R9 | 2 | [CF18JT20K0](https://octopart.com/cf18jt20k0-stackpole+electronics-19205697) | 20K OHM 5% 1/8W | | R8 | 1 | [CF18JT12K0](https://octopart.com/cf18jt12k0-stackpole+electronics-19205652) | 12K OHM 5% 1/8W | | R10 | 1 | [CF18JT220K](https://octopart.com/cf18jt220k-stackpole+electronics-19205700) | 220K OHM 5% 1/8W | | R11 | 1 | [CF18JT1K20](https://octopart.com/cf18jt1k20-stackpole+electronics-19205676) | 1.2K OHM 5% 1/8W | | R13 | 1 | [CFR-25JB-52-150K](https://octopart.com/cfr-25jb-52-150k-yageo-22569037) | 150K OHM 5% 1/4W | | R17 | 1 | [CF14JT2K20](https://octopart.com/cf14jt2k20-stackpole+electronics-19205454) | 2.2K OHM 5% 1/4W | | R18, R19 | 2 | [CF18JT1K00](https://octopart.com/cf18jt1k00-stackpole+electronics-19205674) | 1K OHM 5% 1/8W | ### Capacitors | Reference | Qty | Part | Description | | --------- | :-: | ---- | ----------- | | BC1, BC2 | 2 | [K153K10X7RF5UH5](https://octopart.com/k153k10x7rf5uh5-vishay-44033224) | 0.015 µF 50V Ceramic Capacitor | | C1 | 1 | [ECE-A0JKA101I](https://octopart.com/ece-a0jka101i-panasonic-15327038) | 100 µF 6.3 V Electrolytic Capacitor | | C2, C3, C10, C11,
