| Characteristics | LattePanda Alpha | Libre Computer Amlogic boards — libre-amlogic (flagship: Le Potato AML-S905X-CC) |
|---|---|---|
soc_cpu | Intel Core m3-7Y30 (Kaby Lake-Y), 2 cores / 4 threads, 1.0 GHz base – 2.6 GHz burst, x86-64; 4.5 W TDP (CNX). Intel product page: (linked from CNX article) | — |
gpu | Intel HD Graphics 615, 300–900 MHz (docs). HDMI output, DisplayPort via USB-C, eDP for internal panels; 4K capable (Wikipedia) | Arm Mali-450 MP5 (penta-core, Utgard generation). Mainline 3D support is the open-source lima DRM driver, present in the kernel tree (drivers/gpu/drm/lima). |
co_processor_i_o | Microchip/Atmel ATmega32U4 — the same MCU as the Arduino Leonardo ("Coprocessor: ATmega32U4" in the docs spec table; "contains an ATmega32U4 chip on its board (also known as Arduino Leonardo)" — | — |
ram | 8 GB dual-channel LPDDR3-1866 (docs: "8GB Dual Channel"; LPDDR3-1866 per CNX) | 1 GB or 2 GB DDR3 (v1); Sweet Potato v2 uses 2 GB DDR4 (CNX 2017 / CNX 2023). |
storage | 0 GB (Alpha 800) or 64 GB eMMC 5.0 (Alpha 864); MicroSD slot; M.2 M-key socket, NVMe/SATA, PCIe 4×; M.2 E-key socket, PCIe 2×/USB 2.0/UART/PCM (docs spec table; E-key also exposes I2C per | microSD slot (UHS, SDR104-capable; mainline DTS: 4-bit bus, max-frequency = <50000000>, cap-sd-highspeed) + removable eMMC module socket (8-bit, HS200 in the mainline DTS: mmc-hs200-1_8v, 200 MHz; CNX advertises HS400 modules — see note). Sweet Potato v2 adds 16 MB SPI NOR with boot-select switch. |
networking | Gigabit Ethernet (PCIe, Wake-on-LAN supported), Wi-Fi 802.11ac 1×1 dual-band 2.4/5 GHz, Bluetooth 4.2 (docs spec table) | 10/100M Ethernet only (no WiFi, no Bluetooth onboard — a key cost-cut vs. Raspberry Pi). Sweet Potato v2 adds an optional PoE header (CNX 2023). |
usb_video_audio | 3× USB 3.0 Type-A; 1× USB Type-C (Power Delivery input + DisplayPort + USB 3.0); HDMI; 3.5 mm audio jack; RS-232 on header (docs) | — |
gpio_expansion_headers | 2× 50-pin headers carrying I2C, I2S, USB 2.0, RS-232, system-control pins, EC (BIOS) pins and the Arduino-compatible pins (D0–D13, A0–A5 style, driven by the ATmega32U4) — CNX 2017-12-08 article + ("2x 50p GPIOs including I2C, I2S, USB, RS232, UART, RTC"). Pinout diagrams: (front) and back variant. - PWM, 10-bit ADC and all other electrical characteristics of the I/O pins follow the ATmega32U4/Arduino Leonardo datasheet, since the pins are wired to that MCU ( | — |
power | USB-C PD input (official 45 W PD adapter) or 12 V DC via JST PH2.0-4P header, 7.4–15 V accepted; LiPo battery port (10-pin, 2–4 cells); recommended supply 12 V / 3 A. Boot ≈ 10 W, typical operation ≈ 5 W without heavy load — | 5 V via micro-USB OTG port (v1; the official kit shipped a 5 V/2.5 A PSU — CNX unboxing); Sweet Potato v2 uses USB-C 5 V/3 A (CNX 2023). Power can also be fed via the header (community practice, hub "Powering the Le Potato" thread). |
dimensions | 115 × 78 × 14 mm (docs spec table and product page). | — |
cooling | passive heatsink or active fan (fan ships in the box on later SKUs; "adjustable cooling fan header" per CNX). | — |
operating_temperature | not stated on the fetched official pages. | — |
soc | — | Amlogic S905X (Meson GXL family), quad-core Arm Cortex-A53 (ARMv8-A, 64-bit) @ 1.5 GHz, with Amlogic Video Engine 10 VPU. |
usb | — | 4× USB 2.0 host ports (CNX 2017 spec list and the mainline U-Boot board doc both say 4×; v2 adds an extra USB 2.0 header). |
video_out | — | HDMI 2.0 (4K/60 per U-Boot docs); v1 also has a 3.5 mm TRRS AV jack with CVBS (480i/576i) — removed on v2. CVBS and HDMI are described in the DTS (composite-video-connector, hdmi-connector). |
audio | — | HDMI audio, AV-jack stereo, SPDIF header, I2S header; onboard DIO2133 analog amplifier for the headphone jack (explicit DTS node dio2133: analog-amplifier). |
gpio_expansion | — | - 40-pin Raspberry-Pi-compatible header ("7J1" in the schematic; every line is named 7J1 Header PinN in the mainline DTS) with I2C, SPI, PWM, UART, 5 V, 3.3 V. - GPIO banks GPIOAO / GPIOH / GPIOE / GPIODV / GPIOX (bank names visible in the DTS gpio-line-names). Logic level 3.3 V; no exposed pin is 5 V-tolerant — official answer: "No exposed pins are 5V tolerant on any SBC. Do not put 5V on GPIO pins." (hub.libre.computer topic 3242). - Separate ADC + I2S header (CNX 2017); the GX SoC's SARADC is exposed via the mainline meson-saradc IIO driver. - IR receiver onboard; jumper selects HDMI CEC vs GPIO on one header pin (CNX 2017). - LEDs: green system-status LED (DTS: panic-indicator) and blue LED (DTS default trigger: heartbeat) — DTS. - Debug console: UART on the header, stdout-path = "serial0:115200n8" in the DTS; Armbian uses SERIALCON="ttyAML0" (lepotato.conf). |
form_factor | — | Raspberry Pi 3 board layout/size (CNX 2017). |
