TrimUI Brick Pro Review: The 4:3 Pocket Rocket With Hall Sticks

A 324 PPI laminated 4:3 panel, Hall-effect sticks and HDMI-out in a 236 g brick. We put the TG4070 through its paces.

The original Brick was a lovely little thing with one obvious hole in it: no analog sticks. TrimUI’s answer wasn’t to make a bigger Brick — it was to make a denser one. The Brick Pro keeps the chunky, pocketable silhouette, then stuffs in dual Hall-effect sticks, a 324 PPI laminated 4:3 panel, video output and Bluetooth.

It is, on paper, one of the most complete sub-flagship handhelds anyone has shipped. Let’s find out where the seams are.

TrimUI Brick Pro front view showing the laminated 4:3 display

The 4:3 panel is a statement of intent

Widescreen handhelds are a compromise dressed up as a feature. Almost nothing you actually want to play on a retro device was made for 16:9 — so on a widescreen panel you either stretch it (crime), pillarbox it (waste half your glass), or squint.

The Brick Pro just refuses the premise. 3.95 inches, 1024 × 768, native 4:3, fully laminated, 324 PPI. Every 4:3 system fills the screen edge to edge with nothing left over.

SystemNativeOn a 1024 × 768 panel
NES256 × 2403× = 768 × 720, near-perfect fit
SNES / Genesis256 × 2243× = 768 × 672, clean and huge
Game Boy / GBC160 × 1445× = 800 × 720, gorgeous
GBA240 × 1604× = 960 × 640, sharp with room to spare
PS1320 × 2403× = 960 × 720, fills the panel
Nintendo DS256 × 192 ×2Stacked layout suits 4:3 perfectly

That table is the entire argument for this device. Integer scaling everywhere, no stretching, no wasted glass. And at 324 PPI, the pixel grid disappears — you get the look of a CRT-adjacent image with the stability of a modern LCD. Lamination means no air gap, so the picture sits right on the surface and blacks don’t wash out under a lamp.

The one caveat: it’s 3.95 inches. Coming from a 5-inch device, the first ten minutes feel cramped. By day two you stop noticing, because density is doing the work that size used to.

Hall-effect sticks, finally

Two JF15 Hall-effect sticks, both clickable for L3/R3. This is the upgrade that matters most over the wider TrimUI lineup, which still ships conventional potentiometers.

Hall sticks read position with a magnet and a sensor instead of a physical wiper scraping a resistive track. No contact means no wear, which means no drift — the failure mode that kills every other handheld eventually. On a device you intend to keep for years, this is worth more than a spec bump.

ControlNotes
D-padClassic TrimUI feel — tight pivot, confident diagonals
Face buttonsShort travel, quiet, well-spaced for the size
Analog sticksJF15 Hall-effect, clickable (L3/R3), low-profile
ShouldersL1/R1 + L2/R2
VibrationSingle-channel motor
LightingRGB

The sticks are necessarily small and low-profile — this is a 22 mm-thick brick, not an Xbox pad — so they’re best for camera control and analog nudging rather than twitch shooters. Having L3/R3 as real clicks matters more than you’d think for N64 and PSP mapping.

Ports: the quiet superpower

Two USB-C ports, and they do different jobs:

PortWhat it does
Bottom USB-CCharging (10 W) + PC data
Rear USB-CUSB host — controllers, keyboards, FAT32 flash drives
Video outDP Alt Mode, up to 1920 × 1080 @ 60 Hz

DP Alt Mode is the headline here. Plug the Brick Pro into a TV with a USB-C-to-HDMI adapter, pair a controller over Bluetooth 4.2 or plug one into the rear host port, and you have a genuine living-room console. For a device this size and price, TV-out plus wireless pads is a properly nice trick.

Storage is equally relaxed: 8 GB eMMC for the system, microSD up to 1 TB for everything else, and USB host that’ll read a FAT32 stick if you want to sideload without pulling the card.

Performance: A133P realities

TrimUI Brick Pro held in both hands, mid-game

The Brick Pro runs the same Allwinner A133P at 1.8 GHz with a PowerVR GE8300 at 660 MHz that powers TrimUI’s larger devices. One meaningful difference: this one uses 1 GB of LPDDR3, not LPDDR4X. Same capacity, older and slower memory standard — you won’t notice it in 2D, but it’s part of why the heavier 3D tier stays stubborn.

SystemVerdictNotes
NES / SNES / Genesis / TG-16FlawlessShaders and overlays on top, no sweat
GB / GBC / GBAFlawlessThe best-looking GBA I’ve used, full stop
Neo Geo / CPS1-2-3Flawless4:3 arcade content is this panel’s home turf
PS1ExcellentFull speed with upscaling headroom
Nintendo DSVery goodStacked screens fit 4:3 beautifully
N64Good, title-dependentThe usual per-game settings dance
PSPGood, title-dependent2D and light 3D fine; heavy 3D wants frameskip
DreamcastPlayable, mixedSome titles sing, others stutter
SaturnRoughEmulator cost, not silicon
PS2 / GameCubeNo1 GB of RAM ends the conversation

The shape of it: everything through PS1 is a solved problem and looks spectacular on this screen, DS is a genuine pleasure, and N64/PSP/Dreamcast is the band where you’ll be tuning. If your library lives in 2D, the Brick Pro is comically overqualified.

Software

Stock is Trim-UI Linux on a 4.9 kernel — boots fast, sleeps and resumes reliably, and TrimUI’s own menu has matured a lot. Twelve interface languages out of the box is a nice touch that most competitors skip entirely.

But the real reason to buy TrimUI hardware is the community around it. The A133P platform has an active custom-firmware scene, so this is a device that keeps getting better rather than shipping and going quiet. Whatever you run, buy the console from the official TrimUI store and put your library on a name-brand A2 microSD — leave the 8 GB eMMC to the system.

Battery, size and feel

5,000 mAh behind a 3.95-inch panel is a much better ratio than the same cell behind a 5-inch one, and it shows — the quoted 5–10 hour range is wide because the workload range is wide:

UsageRough runtime
GB / GBA / 8-bit, low brightness, RGB offToward 10 hours
SNES / PS1 / DS, medium brightnessComfortably in the middle
N64 / PSP, high brightness, RGB onToward 5 hours

Charging is 5 V / 2 A — 10 W, with CC charging supported. Not fast, but a meaningful step up from the 7.5 W you get on some siblings, and enough to refill overnight without thinking about it.

At 236 g and 130 × 86 × 22 mm, it’s dense in the hand — heavier than it looks, in the reassuring way. It’s a jacket-pocket device rather than a jeans-pocket one, and the thickness that makes it a “brick” is exactly what makes it comfortable to hold for an hour without grips.

Brick Pro vs Smart Pro

They share a chip and a price neighbourhood, so this is the comparison that actually matters:

Brick Pro (TG4070)Smart Pro (TG5040)
Screen3.95” 4:3, 1024 × 768, 324 PPI4.96” 16:9, 1280 × 720, ~296 PPI

Bluetooth4.2 + EDR—

Weight236 g~162 g
Best for2D, arcade, GBA, PS1, DSWidescreen content, PSP, bigger picture

The Brick Pro is the better retro machine — 4:3 native, drift-proof sticks, TV-out. The Smart Pro is the better big-screen machine. If most of your library predates the sixth generation, the Brick Pro wins comfortably.

Verdict

TrimUI stopped chasing specs and built the handheld the retro library actually wants: 4:3, dense, drift-proof, and pocketable.

The Brick Pro’s compromises are all in the same place — the ceiling of what an A133P with 1 GB of LPDDR3 can emulate. Everything below that ceiling is executed close to perfectly, and that’s most of what anyone plays. The Hall sticks and 1080p video output are the kind of features that usually cost twice as much.

If you’ve been holding out for a small handheld that doesn’t feel like a compromise, this is the one to buy.
