| ====== Hardware ====== |
| * [[debug-uart|Debug-UART]] |
| * power-on: hold power-switch 10 seconds, without power-switch: [[http://forum.banana-pi.org/t/bpi-r2-boot-power-suppy/3647/47|Forum]] |
| * solder bridge next to power switch. Can cause problems since poweroff-feature. To fix this blacklist pmic-keys-module or uninstall acpid package see [[https://github.com/frank-w/BPI-R2-4.14/issues/35|issue 35]] |
| * input 5V to OTG |
| * poweroff (4.14.53+) needs acpid package for power-button (command works without it) |

| * emmc on v1.2 is maybe from vendor SEC which needs different pinctrl setting (pu/pd) in uboot to be recognized: [[https://forum.banana-pi.org/t/problem-trying-to-use-emmc/11253|forum]] issue was introduced in u-boot 2022.04 and fixed with patch from daniel (for 2023.07) |
| * wifi-chip onBoard: MT6625 [[http://forum.banana-pi.org/t/support-onboard-wifi-module-mt6625-in-linux-kernel-4-4-70/3718/|Forum (dev)]] [[http://forum.banana-pi.org/t/2-4ghz-and-5-6ghz-wifi-working-fine/3844/|Forum (usr)]] |

| ===== additional hardware ===== |
| |
| * Power-supply: 12V/2A recommended,plug coaxial: 2,1 x 5,5 mm [[https://www.reichelt.de/Festspannungsnetzteile/GS25E12-P1J/3/index.html?ACTION=3&ARTICLE=161621|Reichelt]] |
| * microSD-card (>=8GB): Sandisk Ultra 32GB |
| * WLAN-antennas: 5dBi mit rp-SMA auf IPEX/u-FL Kabel |
| * PCIe wifi-card: [[http://forum.banana-pi.org/t/ac-wlan-pcie-card/|Forum]] => [[wlan#mt76|MT76]] |
| * case: |
| * official: [[http://forum.banana-pi.org/t/banana-pi-bpi-r2-premium-aluminum-enclosure/4119|alu-case]],[[http://forum.banana-pi.org/t/banana-pi-bpi-r2-arcylic-case/4283?source_topic_id=4119|acrylic case]] |
| * inofficial [[http://forum.banana-pi.org/t/3d-designed-case-for-r2/3906|files for 3D Printer]] |
| * heatsinks: |
| * mt7623: 20x20mm |
| * mt7530: 14x14mm (like rpi soc) |
| ===== cables ===== |
| |
| ==== wifi ==== |
| |
| * rp-SMA to IPEX/u-FL cable for wifi-antennas |
| |
| {{:bpi-r2:wifi-connector.jpg?direct&200|}} |
| ==== SATA ==== |
| |
| * [[https://m.ebay.de/itm/Micro-JST-2-54mm-2-3-4Pin-Stecker-Buchse-Stecker-Stecker-Crimps-x-60-SETS/252846562355|2,54mm XH 2pin/4pin]] for SATA power [[http://www.ebay.de/itm/Banana-Pi-SATA-Daten-und-Stromkabel-Kabel-/263090662637?hash=item3d416ceced:g:pyIAAOSwRvdZaqdc|or 2-Pin combined with SATA]] |

| |
| it works with GND next to power (1+2,3+4). 12V is yellow, 5V is red |
| |
| both jacks near sata-connector have voltage, also if R2 is "halted", the fan-jack (near IR-receiver) had no direct-current output in my tests (4.14), this seems my gnd there is broken...with another gnd i have the 5V output |
| ==== battery ==== |
| |
| * <del>1,25mm SH 6pin for battery [[https://de.aliexpress.com/item/Free-shipping-10PCS-Single-End-SH-Pitch-1-25mm-15cm-28AWG-0-36cm-Micro-Wire-To/32801094713.html|AliExpress]], no circuit known</del> battery-connector does not work [[http://forum.banana-pi.org/t/battery-cable-circuit/3737/9|see here]] |

| ===== mount ===== |
| * wifi mPCIe-card bolted with M2x10 screws and knurled nut + 2 x washers of Polyamid (isolation+protection of the board) |
