Librem5¶
Two early batches (Birch and Chestnut) of Librem 5 are already in the hands of backers and developers. Another batch, Dogwood, is expected in March 2020 and then a mass produced one, Evergreen, in Q2 2020.
| Component | Hardware | Comments |
|---|---|---|
| SoC | iMX8M Quad CPU | * The non-free DDR4 controller firmware is handled by a M4 core present in the SoC and will be on a separate flash chip (so Replicant won't have to redistribute it). * The bootloader (u-boot + ATF) is going to be fully free and redistributable by Replicant. |
| GPU | Vivante GC7000Lite | * Supported in mainline Mesa by etnaviv driver. |
| Display | 5.7″ 720x1440 display | |
| Memory | 3GB RAM LPDDR4-3200 | |
| Storage | 32GB eMMC microSD slot |
|
| Wireless | Redpine RS9116 802.11abgn 2.4 Ghz / 5Ghz + Bluetooth 5 & BLE | * Firmware loaded from an on-board flash memory. |
| Audio | Wolfson Media WM8962 | |
| Baseband | Gemalto PLS8 or Broadmobi BM818 on replaceable M.2 card | * Single SIM. * Both modems use QMI and AT. * Connected via USB and I2S. * On-modem GNSS receiver has disabled antenna. |
| GPS | TESEO LIV3F multiconstellation GNSS receiver | * NMEA over UART |
| Motion sensor | STmicroelectronicts LSM9DS1 | |
| ALS/proximity | Vishay VCNL4040 | |
| Smartcard | 3FF format smart cards | * Early batches use 2FF format card. TODO: * How is it connected? * What Android frameworks exist for smartcards? |
| Back Camera w/LED flash | 1/3" 13Mpx CMOS sensor, S5K3L6XX; 4224×3136 active pixels; 30fps @4K, 60fps @FHD, 120fps @HD; focusing range: 10cm - ∞ @AF; FOV: 81.5° |
* No drivers yet. |
| Front Camera | 1/4" 8Mpx CMOS sensor, YACG4D0C9SHC; 3264×2448 active pixels; 30fps @QUXGA, 60fps @FHD (Crop), 90fps @HD; focusing range: 28.9-65.0cm; FOV: 83.3° |
