SanDisk Sansa Clip

Current Status

Rockbox runs on the Clip v1, Clip v2, Clip+ and ClipZip? models, and is generally stable enough to use.

Installation is safe and reliable on all of these except the Clip v2; for a minority of Clip v2 players, attempting to install Rockbox will brick the player, and recovery involves delicate hardware modifications. If you are not willing to disassemble your player, consider using a model other than the Clip v2 with Rockbox.

For details see SansaAMS.

How to Identify a Clip (v1/v2), Clip+ or Clip Zip

The original Clip has a round scroll-wheel control, a 128x64 yellow/cyan monochrome OLED display, a mini USB connector, and no microSDHC slot. A v1 Clip has a firmware revision starting with 01, while a v2 Clip will have a firmware revision starting with 02.

The Clip+ has a square directional-pad control and a microSDHC slot, but retains the monochrome OLED display and mini USB connector of the original Clip.

The Clip Zip has a rectangular directional-pad control, a 96x96 full-colour OLED display and a micro USB connector, but retains the microSDHC slot of the Clip+.

Sansa v2 firmware file

The SansaAMSFirmware page explains the firmware file details needed for porting of Rockbox to Sansa v2 models.

A growing collection of extracted firmware files can be found at Daniel's Sansa Series v2 Firmwares

Sansa Clip Zip port status

The Sansa Clip Zip works fine for day-to-day audio playback.

Stuff that still needs work (as of 2011-12-31):
  • user manual (needs at least all the screenshots, can be made in the simulator).

Plugins that need work:
  • brickmania: create graphics for bricks (9x4 pixels), paddles, powerups (?x? pixels), game over graphic
  • sudoku: create graphics for numbers and fix layout


Sansa Clip Zip

Pictures of the insides of the Sansa Clip Zip:

According to the diagnostic mode of the original firmware, the display can apparently be one of two types: Visionox or WiseChip. The Visionox display could be a Visionox M00230/M00231 OLED module, the display controller is unknown. The WiseChip display appears to be controlled by a SEPS114A OLED controller. The tuner chip is the SiLabs Si4703, which is the RDS capable brother of the SiLabs Si4702 (used in several other Sansa players).

Clip+ variants

The Clip+ comes is a couple of variants:
  • There are two slightly different OLED controllers, the new one no longer needs a 2-pixel offset and is different w.r.t. brightness/contrast setting. This is auto-detected in Rockbox.
  • The FM tuner chip can vary, either SI4702 (old) or RDA5802 (new), this is also the case on fuze v2. The FM tuner chip is auto-detected by Rockbox. The variant is visible in the HwInfo diagnostic screen in the original firmware.
  • The settings for the SD card controller can vary, this is also the case on fuze v2. In the HwInfo diagnostic screen in the original firmware, this can be seen as either "HERMON" (old) or "COMBO4E" (new).


On Sansa E200v2's there is an 8-pin JTAG port (see with probably the following pin layout:
1: VDD    +
2: TCK    JTAG Clock
3: TDI    JTAG data in
4: TMS    JTAG test mode select
5: nTRST  JTAG test reset, active low
6: TDO    JTAG test data out
7: nSRST  System reset, active low
8: GND    -

The Clip also has 8 pins below the USB connector (on the other side of the PCB), probably this is JTAG too but has not been verified.

The Clip+ uses the following JTAG layout:
ClipPlus JTAG pinout


       8           GND
    7              nSRST
       6           TDO   (high impedance)
    5              TCK   (pulldown)
       4           TMS   (pullup)
    3              TDI   (pullup)
       2           nTRST (pulldown)
    1              VCC

Battery discharge curve

Clip battery discharge curve made with the battery bench plugin, using SVN r19262. Done with processor idling at 240 MHz, display off, shutdown voltage at 3.3V. After the Clip had shut down in rockbox, it would still boot up in the OF, showing 0% battery left. The voltage vs. time curve is fairly linear down to about 3.65V, at which point the voltage starts dropping very quickly.

Clip v2

In Auto and MTP mode, idProduct is 0x7434. In MSC mode, idProduct is 0x7435.

Auto mode looks like v1 dump above. MSC mode defines a standard Mass Storage interface with two bulk endpoints, and MTP defines a vendor-specific protocol.
